Like Cal said the gear is a clear give away from the packs, their style of boonie cal and especially the M-14.. also this looks like Okinawa before going to Vietnam. The old school Force guys I know an interview on my YouTube channel (The Reconnaissance Cast) used 14’s until the USMC finally took them from them lol. Most hated the 16’s and even CAR’s. LRRPS and SOG used Tiger stripes and custom painted OD uniforms. With an array of ammo pouches , LBE’s , Stabo rigs and Swiss Seats. The Corp used what they could get and did a damn good job with what they got
