Interesting - has the HEI ammo ever been used in combat? Serious question (not yanking your chain), I'm curious - because everything you ever see or hear about the A-10 is tank busting with those API rounds.
I recall seeing an interview with an A-10 pilot who got an air-to-air kill when he came across an Iraqi helicopter (I'm thinking the First Gulf War, but I could be wrong). Anyway he said something like 'I gave it a five second burst and there wasn't much left...'.
