Rocket Propelled Grenade (RPG)

It is basically a tube that can be shoulder-mounted and can fire an explosive Grenade/Rocket from it. RPGs were first created in WW2 to help dispose of enemy tanks.

The main problem with fighting tanks was the large amount of armour protecting them, early attempts to pierce through it were extremely high caliber bullets fired from large rifles, this however proved ineffective and the recoil produced was enough to break a man's shoulder and in some cases kill the soldier firing it, later the Germans resorted to old, well-known laws of physics. To cancel out the large recoil of firing an explosive a stream of fire or gas was released out of the rear of the tube to level out the projectile momentum, this design was quite old, dating back to WW1. The first successful break through was with the Faustpatrone, a very light, cheap, and easy to make and manufacture in large numbers; although it was highly dangerous, in some cases soldiers behind it could become engulfed in flames. Later break throughs came with the highly successful Panzerfaust. Now theRPG-7 is the preferred weapon of choice by combatants throughout the world, although not capable of penatrating modern tank armour it is still a large threat to armoured personal carriers.
