I went up to do some ground ordinance training, Mk82's 84's ZUNI Rockets did great, I scored a direct hit on 3 BTR's with Rockeye. Watched from the F6 perspective watched them get surrounded in smoke but zero damage was registered, Put a MK 84 in the center of the cluster no damage, a few soldiers killed. Landed a direct hit with a MK 82 the BTR died. I don't know what to blame? Is a BTR tough enough to survive a bombs that close or a direct hit with a cluster? or is something wrong with the munitions?
