Without wanting to excuse a Blue-On-Blue:
If one country supplies the lion's share of all aircraft types, in every war in living memory, with other countries supplying pitiful contributions of niche capabilities, then the God of statistics comes out to play.
Simple averages very quickly tell you who will be the unlucky bugger who has every intention of helping out the lads on the ground, but sadly doesn't.
Truth is, the FAC obviously wanted cannon fire, and no-one else was there to give it. Incredibly sad news for the deceased, family and friends...and not exactly pleasant for the Hog driver.
