I have one more left, kill 1 ground target with the LA-7.
I spent over ten minutes pounding a bunker with my IL-2M's 4x 100 kg bombs, I managed one bunker that game luckily everyone was a fighter apart from me & my clanmate.
I got my P51-D ground kill by crashing into a boat (fired a few rockets beforehand). A B17 had bombed it previously though
what made it better was it was my first attempt at getting a ground kill with the P51-D.
I wish that there was some AAA around the bunkers which the fighter bombers could clear out before the big bombers arrived could add another tactical side to the mode and some easier ground kills for the unlocks.
