Offensive: This helicopter can take out infantry fairly easy, a Hastatus Sniper or Prime going down in 1 chemical shot and flamethrower infantry going down in two shots. Best to use for infantry countering.
Defensive: This helicopter's damage is extremely low against tanks. Use anti-air units or just ignore it and deploy your tanks. Other units that could take it down are the Comrade Zero (whic is ironic because it takes down infantry) and the Liang's Reapers (more irony)
