Uwanda & Mugabia: Growing Scope & Shrinking Scale

As I prepared to run the next couple of ground battles in the war between Uwanda and Mugabia, I realized that the battles have become larger than what I originally envisioned for the campaign, and potentially unmanageable in 15mm on my table. 

Originally planned as primarily infantry battles with platoons of vehicles here and there, I'm now facing two battles that could feature a half dozen or more company sized units with other supporting elements.  I don’t think that my 6’ x 9’ table can handle upwards of a hundred vehicles and associated infantry roaming about on it, and still have room for maneuver.  So, I'm going to try switching over to 1/285 scale or 6mm figures for some of these larger battles.  I've already ordered infantry, and a few vehicles and aircraft to paint up, and with any hope, will be able to move this process along quickly.

Terrain-wise, I’m not too bad off.  I need to make a few buildings, but have some Arab style buildings that gives me a start, and have both the basic terrain tiles (many are already used with the 15mm games), and trees that will work. There are a few items that I’d have to add otherwise, but at 6mm, none of it should take too much time.

My only real concern is that the games might lose some of their personality.  I'll still be using the same character/leader mechanisms, but I'm worried that since the infantry will be based as sections on multi-figure stands, that the game could become sort of impersonal. We'll see how it goes, if the flavor seems to leak out of the games, I'll have to find another solution.

In the mean time, I still have a couple of air battles to play out, and can spruce up some of my old NATO/WarPac Micro-Armor.

I'll post updates of my progress.

AAR29: A Good Showing by Mugabia

With the exception of the Mugabian counter-attack at Objective 21, which caused Uwanda to alter plans slightly, things had pretty much gone Uwanda's way thus far.  The second day of the war opened with a series of morning attacks by Uwanda's forces, both on the ground and at in the air.  The battle at objective B29 would be key to the success of Uwanda's plans.  Surprisingly, the battle consisted of the smallest forces on both sides to fight on this day.  Uwanda had air cover with two F5As, but no ground attack aircraft committed, and neither side had artillery support.

The black line running roughly down the center of the map is the
 border between Uwanda and Mugabia.  The Battle takes place
 at Objective 29, center right.

Uwanda's forces consisted of:

1 Armored  Company with 13 Sherman Firefly
1 Motorized Infantry Company in trucks with 12 infantry sections and the CHQ
1 Recce Section with two Ferret armored cars.

Uwanda's view of the battlefield, looking generally north.

Mugabian forces:

1 Mechanized Infantry Company with nine squads in BTR152 and the CHQ
2 BRDM in an ad-hoc recce section
2 ZU23/2 anti-aircraft guns towed by trucks.

Mugabia's view looking south.  In the far right, the little 
white puff is a Uwandan Ferret armored car burning.

The Mugabian forces had some time to dig in, and had created two lines of defense, the first a lightly manned screening line, the second a more solid line of infantry, running diagonally towards the first to the extreme right.  The BRDMs would act as a mobile reserve to try to patch any breeches.  The Mugabain commander expected that Uwanda would employ armor, and the best that he could hope for was to embroil any enemy tanks in an close range skirmish with RPG wielding infantry.

From overflights, Uwanda knew that there was a significant infantry force located at the objective, but feared that by the time that they arrived, reinforcements with heavier equipment might be waiting.  The Uwandan commander regretted that one of his two assault groups had been recommitted to fighting elsewhere, as his force was now the lightest of all Uwandan attacking elements, and was in the position of making the deepest penetration into Mugabian territory.

Though still mounted, Sergeant Okoye's recce section was at least now moving at a more reasonable speed and cross country, rather than simply racing to their death on the road.  He intended to follow orders exactly, barely making contact, and then letting the heavier forces do the shooting.  His Ferret slowed to a stop, as it approached a tree line.  "Time to have a look...again", he thought, as he prepared to climb down from the turret.

Uwanda's scouts slowed as they approached each line of trees and bushes separating fields, taking time to scout out the next line of foliage.  Unfortunately both scouts were spotted by infantry, prior to seeing anything, and one was hit repeatedly, first getting immobilized, and then destroyed by RPGs.  The other scout was fired upon, but at much longer range, and skedaddled into cover along the river.

In time, the Fireflies advanced, moving cautiously, trying to find the elusive Mugabian infantry.  After advancing into the field with the destroyed Ferret, RPGs opened up, killing two of the tanks.  Their positions given away, the tanks were free to engage, firing cannon and machine gun, and killing a number of infantry.  Quite a number of RPGs were fired, but most missed as the Mugabian infantry started to fall back.

Fireflies advance, the Mugabians still haven't been sighted.

The advance continues, more Fireflies pass those killed by RPGs. 
Uwanda's infantry follow in trucks at some distance.

During this exchange, another platoon of Fireflies advanced into battle, with Uwanda infantry in trucks following behind.  Finally in range, the Mugabian anti-aircraft gun on the hill opened up on a truck and demolished it and many of its occupants.  Additionally, in rapid succession, three more tanks, including the one ridden by the battlefield commander,  were hit by RPGs during the slow advance.

Despite Fireflies dropping high explosives in close proximity, 
the ZU23 continues to fire.

The remaining tanks focused on the AA gun, as well as, the sources of RPGs.  Though the AA gun got another truck, it and many of the RPG gunners were knocked out of action, and the Mugabians withdrew completely from their first defense line.  However, chaos ensued as some of Uwandas forces continued to follow their last orders, while others reacted unpredictably to the specific events involving them.

RPGs and the ZU23 took their toll.

It took some time for the young infantry captain to gain control over most of his forces, and even then, he wasn't really equipped to coordinate the armor and infantry. 

Most of his infantry had dismounted at Mugabia's first defense line by the time he caught up to them.  He had one platoon remount as a reserve, while troops to his right exchanged long range small arms fire with Mugabian infantry near the road leading into town.  To his left, he had his second platoon advance toward the small hill, now seemingly abandoned by the opposing infantry.

Second Platoon advances toward the little hill.

Third platoon advances into the open area east of the hill, and 
west of the road (lower right).  Second platoon is now engaging 
Mugabian troops on the hill (upper left).

During the lull that came after the command tank was hit, the Mugabian commander had his troops withdraw to the backside of the small hill to the southwest of the town.  He hoped that the cover would force the Uwandans to finally attack dismounted, giving his troops opportunity for a fair fight.  Additionally, if the tanks came again, the few remaining RPGs would be able to engage at short range.

When the Uwandans did advance over the hill, a furious firefight ensued, in which both sides took heavy casualties.  Both sides suffered morale failures, simultaneously abandoning the hill. 

The Uwandan Captain, sent the reserve platoon to try to regroup the remnants of second platoon, while third platoon advanced into the open area just west of the main road into town.  The Mugabians withdrew into the town behind the hill and along the road, during the Uwandan recovery and advance. 

Uwandan infantry withdrew, rallied, and attack the hill a second time.

Once again the Uwandan infantry rushed the hill, engaging in another heavy firefight, and discovering the Mugabian surprise behind the hill, two BRDM armored cars with their heavy machine guns.  Once again, the Uwandan infantry broke, causing the caption to mount up and advance with the remaining tanks to regroup his battered forces. 

Fireflies crest the hill to find the Mugabians nowhere in sight.

All during this time on the hill, Uwandan infantry slowly closed with the Mugabians in the town and along the road, finally gaining an edge, and hitting several of the Mugabian infantry in the town.  As the Uwandan tanks advanced up the hill to engage the armored cars, waiting on the other side, the Mugabian commander decided that it was time to withdraw.  His force had been reduced by half or more, but had fought hard, and stood their ground, when required.

Uwandan infantry west of the road, advance on the town.

The Mugabians took significant losses along the road, 
and finally decided to withdraw. 

Uwanda took the objective, but paid dearly during the process.  This force would not be advancing to the next fight.  Additionally, the captain's after action report, combined with observations from higher on, gave clear indication of the limitations of Uwandan command structure, and the cost of attacking without proper artillery and/or air support.

Sergeant Okoye was confused as he came too.  His last memory was of the flash and the immense burning pain in his legs, then blackness. The medic assured him that his injuries actually weren't too bad, and that he would be okay.  He asked about his driver, and the medic said that he didn't know, but Okoye already knew what the medic wouldn't tell him. 

This was a great game, if a little slow at the start.  The battle took place almost entirely on the "west" side of the road, but the infantry battle for the hill ebbed and flowed with multiple morale failures and rallies, spanning maybe 25 turns or more.

In the end, there were simply too many Uwandan troops and tanks, but the Mugabians fought well.

Losses were as follows:

7x Sherman Firefly
3x truck
1x Ferret

17 KIA
46 WIA

1x Zu 23-2
3x BTR152
1x GA 66


2x Zu 23-2
3x BTR 152
1x Gaz 66

21 KIA
30 WIA

I'm still playing with officer command bonus/penalties for leadership quality, training, etc.  

Uwanda's primary commander was a strong leader, but the infantry captain was inexperienced and hesitant, making him slow to act. He got a one turn penalty to make decisions when changing orders.  this helped give time to the Mugabians to regroup and reposition, during the fight for the hill.   

Mugabias leader was recognized as having great character and was well respected by his men, which gave a morale bonus to his troops.

Probably going to do another battle this Saturday.

Nothing Gets You Painting... having a game set up, ready to play, and discovering that some of your miniatures are missing.  

It all started, just before the weekend, when I had a wee bit of dental surgery.  Nothing outrageous, just enough to make your jaw throb for a few days.  Irritated and distracted by the sensation, the one thing that I knew could distract me from my constant awareness of it, is gaming.  

So I picked up my folder for my 3rd world imagi-nations campaign, took a look,  and thought, "I should be able to get at least three games in this weekend."  I figured out the sequence of the next series of battles,  hurried downstairs, set up the terrain, pulled the Mugabian forces and placed them on the table, pulled the Uwandan forces, and wait a minute...

… Where is the other half of my "company" of Sherman Fireflies?  I need 13,  I know that I painted 14 of them at one point.  I can only find seven of them. What the heck?  I snoop around, confident that they will show up shortly.  Jaw is throbbing.

After some time searching, like better than two hours, I still have only seven tanks.  The Jaw is throbbing.  In years past, my dentist would have prescribed a day of two's worth of prescription pain killers.  I've never used more than two of the buggers in the same year, but even so, because of the opioid epidemic, he no longer prescribes them.  He noted that I might feel "minor distress" as a result.

Yup.  He was right.  I have indeed been visited by "minor distress".


… My tanks are gone.  Just gone.  

Got no clue where they could be.  A couple of years ago, I discovered that all of my 15mm Panzer Is and variants were missing.  The last time that I could remember seeing them was at a convention a few years before, where I ran a France 1940 game.  The drawer was there in my wooden storage box, but mostly empty.  It had some Pz IIs, but no Pz1s, PzJg 1, Befehls-boxes, et cetera, maybe 22-25 vehicles were missing.  It would be hard to have left them there accidentally. They had a drawer in a wooden storage box that I built for my vehicles; so it wasn't a matter of leaving a plastic box on a chair or under a table.  And besides, I didn't use all of them in the game, so some never left the storage drawer.  To leave them, I would have had to pack up everything, and left two dozen tanks setting on an empty event table.  I hate to think that someone walked off with them, but unless my house has a ghost with a thing for German light tanks, I don't know what could have happened to them.  Guess those Pz1s are in trouble now, as the ghost has some Fireflies that will rip them a new one.

Well, I just happen to have seven more castings, assembled, but unpainted, setting in the hopper.  So I got the dudes out, chased down my painting notes from a hundred years ago, and started painting.  they just get a basic paint job with a touch of weathering.  But we had a ton of rain the other day, which means that the basement, no... cellar, we have a cellar, ancient (by American standards) stone walls, kind of dungeon-like; the cellar is damp.  Even with the dehumidifier running, the humidity will just not go away.

So, I thought, I'll slap a first coat on them, and play out one of the dogfights occurring in association with one of the other land battles.  Umm, wait.  I have that game already set up; the fight for Objective B29.  Crap!  Nowhere to play.  

Well, how long can it take to do a basic paint job?  I'm now on day three, and may not finish them in time to play the first game of the weekend, this weekend.  I just did the final touch up of the basic hull color, still wet after 45 minutes.  Not used to this.  

So, here I am, with an entire weekend (actually, three days) actually free, to do nothing but game, and instead, I am watching paint dry, and too distracted to paint other stuff to pass the time.

Did I mention that my jaw hurts?

AAR28: Operations Concluding the First Day of War (The Uwanda/Mugabia War)

I decided to take a break from my post apocalypse gaming just long enough to finish up some loose ends from the Uwanda-Mugabia war, occupying a town and completing a series of Uwandan air attacks on the first day of the war.

The map shows the location of the objectives 
along the border between Uwand and Mugabia.

Objective B6

By late afternoon of  D+1, Uwanda's forces reached the outskirts of Objective B6.  Aerial reconnaissance had shown that the town was occupied by Mugabian infantry with little support, similar to most other towns near the northern portion of the border.

Uwanda's attacking force deployed for the assault, but as they advanced, they discovered that the town had been abandoned by Mugabian forces, who had apparently withdrawn to either objective B10, or more likely B22.

Uwandan forces were received mostly without incident by the local residents who had largely stayed in their homes, and preparations began for the next stage of the advance.

Objectives B7, B8, and B9

Initial plans called for simply bypassing garrison troops located at objectives  over-run by Uwanda's advance.  Uwanda would place small occupying forces in the captured objectives, and move on, with the general belief that the immobility of Mugabia's garrisons rendered them little threat to Uwanda's the occupying forces, and that they would lack sufficient initiative to take on counter-attacks on their own. 

Uwanda's leadership realized that this could change, but believed that they could adapt rapidly enough, to overcome any surprises along the path of advance.

As Uwanda's forces advanced east through objectives B6 and B21, Mugabian forces at objectives B7, B8, B9, and B10 had been cut off from Mugabia proper.  Individually these forces posed little threat, but collectively they could yield more than a battalion of infantry, so it was decided to address them, before they became a problem.

Afternoon recon lead to early evening aerial attacks at  objectives B7, B8, and B9, with the goal being to destroy mobility, leadership, and any initiative that the garrisons might have.  Without vehicle transport, these troops would be hard pressed to move, and less likely to take initiative to do anything futile.  B10 was not attacked for the time being, with the intent, that any withdrawing forces would head in that direction, making them predictable and more easily managed, when the time came to do so.

Aerial Attack at objective B7

Similar to the events at Objective B6, was the result of the air force attack at Objective B7.  Uwandan Skymasters could not find any trace of the enemy finding only a couple of abandoned trucks (which they strafed).

The commander at B7 realized that if attacked, that his tiny force had no hope of surviving the Uwandan advance, so he had his troops hide their trucks and equipment, where they could, and his troops dissolved into the countryside.

Attack at objectives B8 and B9

Badu sat crouched behind the stone wall with his rifle, comforted by the though that his force did not appear to be in front of one of Uwanda's advancing elements.  Additional relief was felt, as he saw the dust plume rising on the road from Objective B8, indicating that the friendly forces from there, were arriving at his location, significantly bolstering the strength of the collective force.

The men around him began to cheer , but were quickly silenced, and started to scurry for cover.  He paused for a moment, watching and listening, and then he heard them, the whining engines of Uwandan Skymasters, following on the heels of the friendly forces.  He simply thought, "Oh no!", as he saw the first bombs released by the enemy jets.

Easterly view of the battlefield.

The Mugabian view looking west.

In the face of the Uwandan advance, Mugabian forces at objective B8 had decided to withdraw to Objective B9, and combine with the smaller force located there.  They happened to be arriving at B9, just as the Uwandan air force also arrived.

Friendly forces arrive from Objective B8.

The HQ element of Force B8 would simply drive through objective B9 without stopping, while most of the unit behind was either destroyed or scattered.

An unfriendly force arrives with them.

As The forces at Objective B9 had no air defense weapons, save their light machineguns, and the two towed anti aircraft guns of the force from B8 were on the road behind trucks.  The first pair of Skymasters line up on the column and released their bombs with perfect strikes, destroying several Mugabian trucks and their occupants.

The second skymaster makes its attack, the bombs 
already marked with the smaller plumes of smoke.

The next pair of Skymasters lined up and strafed trucks that had veered cross country, ultimately destroying three more trucks and many of their passengers.

As soon as the Skymasters had cleared the immediate airspace, Uwandan G91s came in from the north, and bombed the forces deployed on the western edge of the village at Objective B9.  Again, the bombs were perfectly on target, streams of tracers from the Mugabian light machineguns stopped, and only fire and death remained.

The first G91 lines up its shot.

The second G91 comes in...

… and leaves its mark.

The Uwandan jets turned for home, their mission complete, two more Mugabian forces essentially stricken from the order of battle.


Not much of a battle here, just shooting fish in a barrel.  Mugabian light machineguns got no hits, and the Uwandans did the Following damage:

Mugabian Force B8 loses:

7x Truck
42x KIA
16x WIA

Mugabian Force B9 loses:

2x Jeep
2x Truck
27 KIA

Both forces lost over half of their numbers.  The number killed was again disproportionately high due to the type of attack, and the inability of Mugabian forces to tend to their wounded.

And thus, the first day of the war was at an end.

Reflecting on Post Apocalyptic Gaming

I've long had fascination with gaming in a post apocalyptic setting,  with the original "Planet of the Apes" probably inspiring my first thoughts of toys in a post apocalypse.  Despite buying my first figures for my own post-apoc gaming in 1987, it has only been during the last year or so, that I have actually brought this to the table as a full blown gaming project.  Oh, there were a few one-off games over the years, but I just didn't have much to bring to the table until recently.

Though 'The Road Warrior" (1981) seems to have most directly defined the image of the genre, it wasn't until after The Terminator (1984), that I started to see the occasional post-apoc game at conventions.  A little later, I started to see the more sci-fi heavy dystopian games, but rarely what I would truly call games of the post apocalypse.

My experience has been that a significant portion of gamers have interest in, and/or opinion about,  post-apoc environments, stories, and gaming, disproportionate to the frequency of actually gaming the genre.  I find this to be a curious thing, given the number of gamers that enthusiastically embrace a variety of post-apoc movies and books.  It may simply be that the right form of post-apoc game did not, or has not yet, come along at the right time to bring about the "flowering" of the genre.

About ten years ago, I discovered The Post Apoc Wargames Forum, an online discussion forum dedicated to the genre.  Over the years, I've come to appreciate it as an amazing place on the internet.  The membership is exceedingly well behaved, sharing a variety of ideas and photos of some of the most amazing artistry in the hobby.

The work and ideas presented on this forum have greatly inspire me to develop my own post-apoc ideas and interests, and exposed me to a seemingly disproportionately large range of products available to the post-apocalyptic gamer. 

This last thought, about the multitude of products aimed at, or compatible with, post-apoc gaming probably fascinates me more than anything.  For a genre that has such a small presence in my decades of gaming experiences, why are there so many products in the form of games systems and miniature lines. 

I realize that some of these products target "other genres", and simply have utility in what I qualify as post apocalyptic, but in many cases, those genres are still niches that are apocalyptic/post-apocalyptic in nature, and similarly appeal to under-represented segments of the hobby, given the scope of products and the expense to make those products available.

Somebody is buying this stuff, but who is gaming it?  And where are they gaming it?  Though I can find evidence of it on the internet, first person encounters have been rare.  

Maybe most post-apoc gamers are similar to me in that they have had great intensions, but have just never been able to bring the game to the table.  In my own case, I am hoping to start going to conventions again in the near future, and intend to present some post-apoc events, and see what sort of response they get.  Maybe I can stop being my own self-perceived "problem".

In any event, I hope that if you have an interest in post-apocalypse movies and books, that you might consider the gaming possibilities, and that if you are already a post apocalyptic gamer, that you might consider sharing your exploits on the forum linked above, and otherwise within the gaming community.

Finding a New Home: Home At Last (3 of 3)*

Everybody's wounds were healing quickly, aided by both Tinker's skills, and the medical supplies from his med-kit.  After only a couple of days, the Lt suggested that they try to cover some ground, and while much slower than they had been, they still made progress, heading towards wherever they were going.

They travelled for days, canyons gave way to hills, and hills to flat-lands.  They made contact with a couple of villages, trading for some things and learning about the landscape of their new world.  They found that some areas retained many of the place names from the Before, while others were completely different, or simply didn't exist in the Before.

As they continued south, they saw the scattered remnants of the Before, littering the vast emptiness of the wastes.  Many sorts of structures and machine were seen, some of obvious utility, but many raised questions that would never be answered.

As they came into contact with people, they were warned about the Dalworth Texians, and about The Confederation, about places east, west, north and south.  It seemed that everywhere was dangerous and should be avoided.  Curiously, no one had heard of the Colorado Region Federal Defense Complex, which was fine by the Lt and his men.

As they travelled, a question began bothering the Lt.  Were they still "his" men?  By what right did he command them?  Thus far, he had gotten two of them killed, and the rest wounded.   Sergeant Cummings had been second in command, and had saved everyone's butt at one time or another, probably saved all of their lives in this last fight.  And Obradovich, forever the comedian.  The day tinker awoke and looked in the mirror to find that O'B had glued a mohawk made of paint brush bristles to Tinkers big, bald head was...  well... just a memory now.  O'B just made life better, and the Lt hadn't.

The more they travelled, the more they realized just how small their world had been in the complex.  And how little they knew about the world in which they now lived.  The things that they had fought, were known as Greenies, mostly only known as rumors.  They had to watch for other mutations, giant scorpions and other "bugs" mostly.  Then there were the "chompers". described as teeth with legs and roamed around the flatlands in little herds, eating whatever they came in contact with.  Hadn't seen any of those yet, fortunately.  Mostly, in the flatlands, there just wasn't much of anything, dust, rock, and endlessness. 

The emptiness of the flatlands, broken up by a settlement.

After a few days of nothing, they finally saw a settlement in the distance.  The team followed the old road that lead towards the settlement, hoping for a little hospitality there.  Those hopes were dashed, when they heard shots ring out in the distance.  

The Lt with the settlement in the distance.

A shot came from the tower.

The team talked it over, and it was decided that the Lt would head out alone towards the settlement, and see if contact could be made.  If the Lt was shot, it was agreed that the rest of the team was to simply leave.  Everybody agreed to it, but none would leave him, and everybody knew it.

The Lt slung his weapon, and slowly advanced towards the settlement.  After a few minutes, he stopped, at what he thought might be the limits of rifle range.  "His" men impatiently watched, hoping to offer covering fire if shooting started, thought with the exception of Spooky, the sniper, their weapons would have little hope of hitting anything at this range.

The Lt stops at a "safe" distance and waits

After a couple of minutes, two men began to approach from the entrance of the settlement, weapons in hand, the others in the settlement obviously covering their approach.  The situation was very tense, and the Lt particularly hoped that one of the settlers wouldn't panic and loose a shot, triggering an unhappy ending to the situation.

Two men from the settler begin their approach.

The Lt watched as the men approached, the men sizing up their opposites.  They stopped a short distance from each other, and the settler on the left asked, "Out for a walk today?"  The Lt replied that they were travelers looking for somewhere to stop and rest for a couple of days, mentioned their encounter with the Greenies, and offered to trade for whatever they might need.  

"Out for a walk today?"

The discussion went on for some minutes, with the man eventually inviting the Lt and his men to come into the settlement.  Everybody slung their weapons, and  though there was an uneasiness that comes with encounters between good men in the wastes, the danger had passed.

Entering the settlement

After that "cautious" initial contact, the team was well received, and much to the delight of the village, the team decided to stay for awhile, better acquainting themselves with the wastes and sharing their knowedge and resources with the locals. 


As I rolled up this scenario, I thought the Lt's team was toast.  The settlement had three times the men, and the Lt's team had no cover.  But the dice made this an encounter, not a battle, and created opportunity for a new storyline.  Not sure what the future will hold for the Lt, his team, and the settlement, but for now they will rest, continue to heal, and the adventures in the wastes will move elsewhere.

Back in late 2015, I thought that I was just about ready to start my post-apoc campaign, but some minor disaster interrupted that, with the result being that it took about two more years, before I got things going.

Anyway, around that time I started writing up intoductions to my various post-apoc factions, and posted the first one on the Post Apoc Wargames Forum, an introduction to the "Greenies"  my repurposed orks as post-apoc mutants.  Now it is old news, and a bit out of order now, but should be in here somewhere on the blog, so read on about the Greenies, if you haven't done so elsewhere...

My first GW ork purchased around 1989, I think.
He never saw the table as an ork, but now serves as a 
"Greenie" in my post-apoc games.

The "Greenies"

Greenies, as they have come to be known, are a race of bipedal humanoid mutants, the result of a bio-weapon research project that was nuked during the apocalyptic event.

They were to be engineered hybrid organisms, a combination of animal and plant DNA that would produce among other things, an engineered self-sustaining, fighting machine. Elements of the design were to be rapid growth to fighting maturity, large scale organ and tissue re-generation, and self-synthesis of food stuffs for sustenance through exposure to light. The program also hoped to facilitate “osmotic” water absorption, to further minimize logistical support and survivability.

The program R&D was conducted in a hardened lab in the south western United States, which was the recipient of a large yield intercontinental surprise on that dark day. The result was that the test specimens rapidly mutated into a plague that has spread across the land, limited mostly by the need to closely follow waterways. They manifest as intelligent, resourceful killing machines with the single purpose of exterminating humans.

Though information is limited, it is known that Greenies have a two stage life-cycle, starting from seed as a rooted plant,  which develops a seed pod. The pod produces one or more seeds and a juvenile greenie that reaches maturity in a matter of weeks. Greenies are raised in “gardens” in greenie “villages”.

The villages are always located along rivers, streams or lakes, and manifest as a sort of base consisting of one or more gardens, and facilities for making weapons and training greenies in the use of the weapons. They are capable of complex engineering and production of weapons and war materials, have good tactical sense, seem to be able to communicate verbally as well as some sort of telepathic or other means undetectable to humans, and have been known to sing and laugh during attacks. 
Not much is known about their social structure or culture if such a thing even exists. It is not known if they have "families", how or if they are parented, nor how they are educated.
In battle, they have some sort of structure, as lesser warriors follow the direction of "leaders" or "alphas", which tend to be larger and presumably older specimens.  It is not known if groups operate independently, or if they are organized at a higher level.
Thus far, they have shown themselves to be fanatical and merciless in battle, leaving no survivors in human settlements that they overrun.  For now, policy is simply to kill Greenies, whenever they are contacted.  Otherwise, they will kill you.
