Fact is, the Tu-2S is very frail for a bomber... Killed one with just three 20mm hit sprites seen. In contrast, the A-20 is a flying tank. It's vulnerable in the front due to front armor not being modeled (heavy armor plate and armored glass). But, from any other angle it's stout. Along with one other guy, I took off to meet a big raid, mostly Typhoons. They shot off my landing gear, one aileron, the rudder, one elevator, the rear turret, both engines were leaking oil. I shot down three fighters, and had three assists (damned Wirbles!). As I tried to belly-in the A-20, now out of ammo, gas and oil, a Ta 152 nailed me as I was on short final. Nothing else in this game can fight off 15 fighters and absorb that much damage, while remaining flyable.
