ZSh-7AP modification is a ZSh-7A helmet with special mount to which either a targeting designator or NVG could be attached. The mount itself attaches to the helmet via 3 screws in the upper forehead area. This ZSh-7 modification is used by Mig-29 and Su-27 pilots. It could also be issued to helicopter pilots so they could attach NVG to the helmet.   ZSh-7AP helmet - front view. Same view but with visor in the down position. Left view.
