The Apache Attack Helicopter has been a force of nature on the modern battlefield for some time. The military purchases them for a tidy sum of $15.6 million. As expensive as that may sound, they certainly get what they pay for. Equipped with AGM-114 Hellfire missiles and Hydra 70 rocket pods, the Apache can pack a devastating punch. In addition to these weapons, Apache helicopters also make use of a 30mm M230 chain gun with an extremely high rate of fire.
