Calling an assault gun a "tank" is minor. In comparison, the leggings are spot-on, and so is the size of the bazooka. Too much of a tendency among artists of our generation to draw these monster weapons. The WWII bazooka was relatively small, yet it was deadly enough.
A bazooka team that hides, waiting for armor to pass by, is going to know already that a head-on shot is a) not going to penetrate and b) be followed up with a face full of machine gun. Knock out the tread or the engine and you're facing foot soldiers. A bazooka could probably penetrate armor in most places on a Mk. 3 or Mk. 4 tank, but I doubt a bazooka team would bother to go after a Tiger or King Tiger. Those were best left to TDs.
