Alright, I've slacked enough, so heres a basic tech tree, so far, I feel that I want my infantry to be weaker in general but have some better support options that can dig in, I want the faction to be slower, with inferior infantry, but generally superior armored vehicles.
Buildings:
HQ-Produces Buildozers, "Last Sight", does tech upgrades
Barracks-Infantry training ground, produces soldiers, shocktroopers, tank busters, engineers and scouts, as well as HMG's, mortars, Cannons and a light tank and self propelled light RCL cannon.
Factory-Builds Excavator infantry support vehicles, Drak tanks, "arty can" assault guns, silent Death tank destroyers and Gilgamesh heavy tanks.
Supply depot-same or similar to the current alliance faction storage building.
Research Facility: researches upgrades(to be decided)
Airfield-Builds AOP, Screaming Eagle Fighters, and Demon Attack planes.
Defences:
Pillbox-mg in bunker
Tank Turret-tank turret emplacement based on the Drak tank.
Several support weapons can dig in for added defense.
Units:
Buildozer-Builds and harvests.
Infantry:
Soldier-sort of like Grunt, but weaker weapon and HP can be upgraded to carry a single shot short range rocket longer on a slow EP recharge.
Shocktrooper-better then soldier in many ways but more expensive.
Engineer-Armed with SMG that is great at short range, good armor(for infantry) and a flamethrower.
Scout-Sniper unit with long range weapon and good speed, doesn't have one shot kills but can do great long range damage over time.
Flak Gunner-armed with a pistol and SAM launcher, reasonably weak but does good damage to aircraft, can be used against tanks for lower range and damage.
Infantry Support Weapons:
HMG-like minigun, but slower firing and moving in base form, when dug in, has great HP and better ROF(rate of fire) can also shoot against aircraft.
Cannon-Slower moving howitzer, gives infantry a better chance against tanks, can dig into a gun pit to be placed in a cruciform mount
Mortar-like alliance mortar, but once again, inferior range and damage but better ROF, can be dug in for greater defense.
Vehicles:
Tiny Tim light tank-weak tank thats roughly equal to IFV, better base weapon and armor but no rockets and worse speed can shoot anti air.
Spider SPRCL-reccoilless gun on underarmored chassis, poor armor, HP, ROF, and speed but great range and damage for early game, can deploy for better health and ROF.
Drak Tank-good medium tank with good armor, gun and health but low speed, also more expensive. has a small one shot flamethrower that takes forever to recharge.
Excavator support vehicle-based on the Drak chassis, has machineguns and can shoot against aircraft and infantry, can repair tanks, maybe make defenses and if possible in MG, give infantry a buff.
"Arty Can"-SP gun on Drak chassis, great gun, better armor, but slow and gun can be a waste against infantry, mostly meant against buildings and in a pinch, other tanks.
Silent Death TD-Also based on Drak Chassis, long gun and AAMG for self defense, horribly weak against infantry but eats tanks for breakfast.
Gilgamesh heavy tank-(hopefully) best tank in game, very expensive and slow but great gun and armor, as well as self defense light cannons to mow down infantry, vaguely looks like Tiger (P) model.
AOP-obseration plane, can fight and do light bombing but mostly just for scouting, otherwise crappy.
Screaming Eagle-Fighter, not particularly great but good in large numbers, best for this armies air defense
Demon-Attack plane, sort of like A-10 and devastating but slow and relatively easy to shoot down due to inadequate air-to-air ability
"Last Sight"-Lieutnant Ostrovich's personal modified Gilgamesh tank, very expensive with two special EP base attacks, a charge attack to crush infantry by running them over and a sniping attack that one shot KO's most vehicles, however, he is only one tank and extremely expensive so not a game changer on his own, just like the air/orbital strike isn't.
I know its a long list, and I might be putting the engineer and tank buster infantry into one class. However. the medium tanks are all on one chassis so pretty easy to make. I'll post pics soon, I even have a back story for the tank ace and why he is a terror for enemies.
