they don't know which way to point
Naw, that's the right way. Unfortunately they aren't that stupid to waste a fair-sized chunk of dough letting someone live-fire something they are completely ignorant about. It's a MANPAD of some sort (not stinger), not a recoilless rifle like in some of the other pics. Probably a SA-7 (old Soviet MANPAD) , the Chinese knockoff, or maybe the "new" Iranian version.
