Armored vehicles maintain one hit of the rocket. The second rocket critical, causes explosion.
The tank will sustain 6-12 rockets.
It seems much for the armored vehicle and the tank.
Armored vehicles are capable to protect from bullets of the automatic machine and a machine gun, but not from rockets.
The tank can sustain several hits. But if one or two rockets get to a back part of a tower, the fighting stock of the tank will blow up.
P.S.
It belongs, somewhat, to all types of rockets, all launchers in an arsenal of Arma3.
