Watched my first ever CSI programme last night and thought it was okay-nothing special. But the main piece of evidence linking a suspect to the firing of a Soviet RPG was the damage the sights did to the eye from the recoil. Now I've never fired anything like this but I would have thought that there would not be excessive recoil as the rocket thrust vents out the back of the launch tube whilst the grenade hurtles out the front of the tube. Is this correct? Or are there other factors?
