Ok.. I've heard that the 190F8 was an "armored" ground attack version of the 190. That armor was either extremely flimsy IRL, or it is not modelled in AH. Or it is modeled but it still does diddly-all for protection.
Was shot down by a PANZER today trying to strafe him. Came in from his 6 OC to shoot at the rear armor, blew up as I flew over him. I did that is, not him. That must be one super powerful 7.92mm MG, either that or the "armor" isn't very good.
I got shot down by either an LVT or an M3, both of which have .50 caliber MGs mounted. I don't think it is to terribly likely that a vehicle that was unarmored would survive a strafing by 20mm cannons long enough to shoot the plane down with a single .50 caliber machinegun. In this case as well, the "armor" on the F8 did jackshit, I heard 3 pings and I was toast.
Also... how much power does a 50kg bomb have? Would it have to land right on top of a vehicle to kill it? I dropped probably 50-60 of them in pairs today on tanks, LVTs, M3s, M8s, M16s, and Ostys. I got several kills, but several took no damage in spite of the fact the bombs landed right on top of them.
