The Apache is crucial to protecting troops when they get into trouble on the ground. We saw this week what happened when a ground patrol couldn’t call in the Apaches. A harrowing episode of BBC3’s Our War depicted a huge ambush on 7 Platoon of the Welsh Guards in which the commander Lt Mark Evison was killed. The Apache also flies as shotgun escort to medical evacuation helicopters. It has more firepower than a flying tank, through Hellfire and Brimstone missiles, an array of rockets, and a machinegun that can fire hundreds of rounds a second, known ominously as “Puff the Magic Dragon”.
