M57 Light Multipurpose Assault Weapon

"The M66 RPG is a sound weapon. The backblast diffusers give it a kick but the launch flash is negligible and it creates a satisfying bang."

- PFC Marcel Williams

The M66 Rocket Propelled Grenade Launcher is a small, reloadable shoulder launched weapon. The launcher consists of a 140mm titanium alloy tube with a rear back blast vent incorporating backblast diffiusers, trigger mechanism and a Small Unit Fire Control Site that provides 4x zoom, fuse settings and various compensators for wind and gravity to aid rangied firing. It fires a 60mm spin stabilised hypervelocity rocket with a impact fused super critical HEAT warhead.

Uses
The weapon is not designed for use against heavy or medium armour, especially not directly, though it stands a chance of penetrating rear, lower or upper armour. It's primary role is the destruction of light vehicles, infantry formations, fortifications such as pillboxes, barricades and destruction of structures such as walls, buildings, etc.

Operation
The M66 RPG is a hollow tube that concentrates the rocket exhaust to create an over-pressure within the tube. This over-pressure propels the warhead at a higher speed than from the specific impulse of the rocket alone.

UNSC Comments
"Its low tech, but its alot more useful than those new plasma anti tank doo-hickeys."

"I saw four of them rush outta the bushes at the edge of the park on the flank of alpha squad. They woulda been toast but we scattered the bits of those Necros suckers with a RPG."

"We saw it coming down the highway god knows how fast, one of their stupid Armoured cares with the armoured nose. We fired off a rocket, timed it well, penetrated its flank armour, put bits of it all over the highway!"
