Tyrant King
First it’s an IFV based vehicle not an MBT as such it’s not armored to the same degree. Generally anything of greater than 30mm has a good chance of penetrating. Even 30mm might get through some spots. If you are firing APFSDS-T 30mm and if doesn’t AP well it’s not large enough to wedge the turret. Remember the whole point is to be a sub caliber rod. It’s going to hit at high speed and shatter. With a little stub sticking out.There're plenty more options that maybe can't penetrate the armor, but do just enough to jam the turret. Then shot trap would matter.
Second if a tank fired at it they wouldn’t waste the rod. They would let it have an HEAT or AMP or if a British tank HESH round. That has the size to wedge but would probably just blow the vehicle apart. But if they confused it for a tank and let the rod fly. That rod would penetrate go in one end and out the other, Like fecal matter through a Water fowl.
