I'm sure no 6,5mm can penetrate that main side plate.
No way any small arms can penetrate the main front plate and destroy the engine.
No idea what he was shooting at. But shooting at the frame/suspension shouldn't let the vehicle blow up.
Ok I guess you can disable a vehicle by doing that, but not blow it up.
Main front plate, side plates. Penetration on these should be impossible with small arms.
Same as above. No way you can penetrate this spot with that rifle.
Ok this is ridiculous. He is not even shooting the sights or something, but the main armor plate of the tower.
A weak spot, but I guess it's at least enough protected small arms can't penetrate that easily.
This is legit, but as you can see bugged. He can't damage the gun of the Marid but with the same method the gun of the Panther.
Legit, he is hitting the optics.
May be legit, but the optics may be protected from behind. But no prob, that is getting too much into detail anyway.
No way. You can see the Marshall is getting damaged. No way you can penetrate that spot with small arms. The engineers of those vehicles aren't retarded.
8:20 and all other rear hits
Getting to the tanks it's speculations as the armors are classified. You may be able to disable the engine with those rear hits, but it shouldn't damage the tank that bad it blows up. There is a disabled engine feature, so use it in this case. But not let it blow up with a single hit.
9:50 and all other front tower hits
Speculation as above, but this is probably the best armored spot of the whole tank. The front tower armor. I don't think you should be able to blow up a tank with 2 hits on the best armored part. I guess the Top 5 MBT could be able to sustain hits at the best armored parts even with a modern 120mm gun. Anyway at least in a game like Arma 3 the best armored parts should protect you against a few hits in my opinion.
