SUSAT

Not to be confused with the ACOG.

The Sight Unit Small Arms, Trilux, or SUSAT, is a 4x optical sight with tritium-powered illumination, utilized at dusk or dawn. The full name of the current model is the SUSAT L9A1. The sight is not designed as a sniper sight, but is rather intended to be mounted on a variety of rifles and to be used by all infantrymen. A similar device is the Advanced Combat Optical Gunsight. In Modern Warfare 2 it replaces the ACOG-Sights for the L86 LSW.

In-Game
The SUSAT replaces the ACOG Scope on the L86 LSW. It appears different to the regular ACOG; instead of having the standard reticule it simply has a central needle.

Interestingly, the Create-A-Class menu treats the SUSAT as the standard ACOG.

Basically, you are all really sad and you lot should really get some resemblance of a life...
