RPG-7 manual states that “no person or ammunition should be closer than 98ft (30m) behind the launcher” – to avoid injuring the former or igniting the latter with the rocket engine gases or with the leftovers of the booster charge. Moreover “there should be no obstacles closer than 6.5ft (2m) behind the launcher” – this is to avoid burning the shooter. So what do we see in this picture? 3 severely burned freedom fighters! (the one on the right may survive though)
But on the other hand, members of the opposing force would surely appreciate the poor level of gun safety training among the guys pictured.
