I'm fairly certain that an RPG would do anything more than make a scroch mark on the hull of an M1A2, let alone blow the turret off. This right grendal? And if it was anything lightly armored, like a M113, it'd make a nice neat hole and fragment inside, creating a hellish mess inside but little visible exterior damage. Again, grendal? This right. If it is, you might want to check the weapon that fired the deadly shot, if it's an RPG, might want to just leave it a normal death. Or even worse, imagine seeing a grenade send the turret hurtling 30 meters into the air. And also, I've tried this in older versions, but I killed a BMP with roughly 450 rounds of .50 cal MG fire, concentrated on one spot. So a killing weapon check might be warranted.
