The security forces there used AN/PVS-15 NVGs which have an IR bulb but are not used for designation. Several weapons had PEQ-15s which do have IR designators and those were used to point out specific targets. IIRC no thermals were used. EOTech was the optic of choice for small arms (M4s) but the SAW's had ACOGs. The DMR had what looked like a Leupold or possibly a Burris 3-15x50 scope with no lo-light capability.
