As said before, it is not the armor, it is where you hit the bomber. Aiming for the fuselage is pretty worthless, as you can take of elevators and even stabilizers, but these kinds of hits dont happen very often and even if they do the plane is still flyable. I like to aim for one of the engines (usually engine #2, the one closest to the fuselage on the right side). Once an engine is out, it makes the plane very hard to fly, and eventually the fire will tear the whole wing off, making the plane impossible to fly. It only takes a two or three thuds from the MK 108 to disable an engine or take of a wing. Though, even with only 3 engines, its still possible to fly a buff home, so try to take the wings off. And, of course, never come up behind it. Almost every B26 sortie I fly, I shoot down one or to idiots that come up behind my plane and try to shoot me down

. The most difficult shot, from a gunners perspective, is when the interceptor climbs or dives onto your bomber. And hit Lanc's and B26's from the belly, they have no ventral or ball turrets. So easy.
