Way back in the deeps of time, I got to fire one of those.
Almost as dangerous to the gunner as it is to the target...
It was designed by the Soviets ... during the Kruschev days.
They placed a slightly different value on human life from we in the West.
A couple of years after the *Bright Star* joint military training exercises between the US and Egypt back in friendlier days, one of the better bits of joint training was an introductory live firing of an Egyptian RPG-7 by US troops. That came to a screeching halt after one such firing ended with the expected loud bang, but on the firing line, with the immediate disappearance of the RPG, the Egyptian instructor, and the US troop firing it. Boobytrapped round, or lousy SovBloc quality control during manufacture? I have no idea.
But there is a wide variance of different ammunition variations of the basic PG-7 antitank rocket, and newer third and fourth-generation rounds as well.
