The mod adds a model of an anti-tank PTRS rifle of the 1941 model to the single game. Remade from the multiplayer model.
PTRS is given to the player automatically when loading any of the missions.
The mod partially changes the models of players, adding Spec Ops-type paints with a night vision device.
Allows you to play as both SAS fighters and S. W. A. T. fighters. To do this, you need to delete/move either images_swat.iwd or images_sas.iwd from the mod folder
