In service since 1986, the Apache AH-64A helicopter was primarily designed as a tank-killer. It was envisioned that fleets of Apache helicopters would be able to counter the Soviet Union's 4 to 1 numeric superiority in tanks on the plains of Europe. In the anti-armor role, the Apache can carry 16 laser-guided AGM-114 missiles. Hovering amongst the trees or behind terrain, the Apache can pop up and engage targets then retreat behind cover. In the close support role the Apache's rocket pods and 30mm cannon can bring devastating firepower to bear against a ride range of enemy units.
