This game is pretty awesome, I spent hours playing this game
What I do want u to do is have levels and maybe more units.
Update list I made
Camouflage Sniper - Extremely far range (maybe 3 trenches distance) One shot kill, slow reload, reload speed 7 sec
Icon - sniper rifle with camouflage
RPG- Splash damage, victim that got a direct hit would die.
Reload speed is 5 sec, damage area is 3 soldiers' length
Icon - RPG
Artillery - different from the mortar. Slow firing, reload speed 10 sec, splash damage. Damage area is 5 soldiers' length. Kills the victim that was hit directly, with the two soldiers on both sides of him also killed.
