There's essentially no recoil from firing an RPG-7...
This is why there's that rocket nozzle looking deal at the back. Also why you really need a certain cubic volume and minimum distance between the back
of the launcher and a wall.
If I remember correctly though the rpg-7 is more suited for confined space firing than many other recoilless weapons because it uses a dual rocket
motor setup where the kicker motor that ejects it from the launcher burns out before the back end of the rocket has left the launcher. It then flies
on a standard parabolic ballistic path with the sustainer rocket motor igniting far enough from the launcher and guy holding it to not require a see
through blast deflector mounted towards the front of the launcher.
This sustainer rocket motor is what imparts the vast majority of the kinetic energy to the projectile, which has the advantage of smaller back blast
area I already mentioned. However it also results in some pretty pronounced disadvantages. The largest disadvantage being that the flight path is a
bizarre double parabola, which results in the reputation it has for poor accuracy.
