Doesn't matter. OP is right. It's irresponsible. Everybody knows that you should always start them out on crew-served weapons so they can learn teamwork, how to take orders under stress, and function as part of a unit. Starting him out on an RPG at this stage is not maximizing his tactical and technical proficiency, or his professional development, and is really just asking for trouble in the long-term. This represents a leadership failure.

No. PG-7 series warheads have both setback, and bore-riding safeties. Which means it's safe until it is fired. But, and this bit is important, it has NO MINIMUM ARMING DISTANCE. Which means, the moment it leaves the tube, the warhead is LIVE. So, the first thing the fuse assembly makes contact with, even if it's something right there in front of you, the warhead will function as designed.
