Ok, they are not really armies so far. Rather a squad each. Of course they are more fun with a background story:
After the dark ages ended on the planet of Strazzel XI its inhabitants coexisted peacefully only for a short time. Not much is known about the first skirmishes. Uncomplete records tell of encounters between random forces with very limited supplies. Over time those random forces expanded as findings of ABS-ore became more frequent. Hostilities arose when there was an argument about what to do with the ever growing ressources. In what is now called the Great Schism two factions formed out of the random inhabitants of Strazzel XI.
On the hand hand there are now the Bricktopian Armed Fighting Forces or short BAFF. They are fighting for snot, finesse and color coordination.
On the other hand we have the Krude Konstruktion Kingdom or short KKKK. They are fighting for blockyness and rainbowism.
Apart from that beliefs of both factions are identical: they love explosions, destruction and general mayhem while their hatred for pink abominations is fanatical.
Also on Strazzel XI there remain a bunch of other inhabitants who have not formed distinguished factions yet. Namely lots of medieval/fantasy guys and the odd pirate.
First of the Bricktopian Armed Forces:
Two of them are armed with laser rifles and three with laser shotguns. The officer carries a combined flame thrower and bolter gun.
And the Krude Konstruktion Kinkdom:
I am not sure yet what their weapons are exactly.
They have an armored transport already:
The red tub! Double duty side armor makes the inside a bit cramped...
Reports suggest that native Strazzelians are building a SHIP somewhere and both squads have been dispatched to check this out later tonight.
