The AH-64A Apache is the United States Army's strongest attack helicopter. The Apache uses the next generation of helicopter technology and provides heavy firepower and close air support to ground units. Its main weapon is a 30mm M230 Chaingun under its nose. It can also carry two AGM-114 Hellfire missiles boxes and two Hydra-70 rocket pods under its wings. These weapons can target all units on the battlefield: infantry and choppers with its machine gun, and tanks and vehicles with its rockets and missiles. Its Hellfire missiles can penetrate even the strongest armor. The units capable of taking down Apaches are BMP-2s, ZSU-23-4 Shilkas, BTR-80s, SA-13 Gophers, and heavy tanks occasionally.
