It replaces the ACOG Scope for the L86 LSW, which is the only weapon that uses the SUSAT. The Create-A-Class menu treats the SUSAT as the standard ACOG Scope. This is due to it having the same in-game effect as the ACOG Scope. It appears different to the regular ACOG Scope, instead of having the standard reticle, it has a central needle, which is not affected at all by an EMP. This scope can be found while playing Estate Takedown in Special Ops and "Loose Ends" in the Campaign, mounted on a L86 LSW in one of the rooms of the safehouse. In Singleplayer and Spec Ops the pickup name for the L86 LSW with SUSAT comes up as "L86 LSW Scoped".
The SUSAT returns under the name of SUSAT Multizoom, available as an Optic attachment for all Primary class weaponry.
The SUSAT has an unusable back up iron sight on top of it.
When using the SUSAT in Call of Duty: Black Ops, the shots land slightly to the right of the needle tip. The error, however, is so marginal that as long as the needle tip is on the target, the shot is guaranteed to hit.
