Four B-25s and two La-5s.
I chewed up two that went down ~5-10mins later while the third I set on fire and popped right after. Another member of the squad crippled the fourth, which also went down ~5mins later (my guess is P/W'ed the drone, bailed, crashed on landing, or maybe ran out of gas from leaks). A couple of the La-5s turned to engage us after we ran through. We put two of them down but not before they got two of mine in return.
If we had better position I may have pressed the attack, but we were JUST level with the bombers and the escorts were above us, so figured better to push through and hope we cleared the other side.
