The SMAW is not your average tracer cartridge, it is two cartridges,

one small cartridge blank inside anothercartridge (7.62x51 brass necked

up to 9mm) which launches the larger than average tracer projectile.

The cartridge is a 9mm rifle cartridge with a High/Low system to have the

cartridge arc more like the rocket path.

This round is part of the Shoulder Mounted Assault Weapon (SMAW)

Anti-Tank Weapon, 83 mm rocket family.

The cartridge is used to match the trajectory of the rocket and is used

to 'sight in' the 83mm Rocket.
