Notice the guys taking a knee in front. Guy on left has a MAG58 with 7.62 NATO cloth bandoliers hanging from him, as well as a stainless 1911 with wood grip panels in an old school leather shoulder holster. Guy next to him has an early 5.56 FN M249 with the aluminum stock. He appears to have the old night vision mount bracket on top of the SAW feed tray cover, with an Aimpoint attached to it. That mount was horrible.
I see several fabricated chest harnesses, old LBV's mixed with LC-1 ALICE gear, Pro-Tecs, Tac lights mounted under the handguards, old Aimpoints, etc. I suspect these pics are from the Mountain Hacienda raid that Noriega never went to. LAV said he used a MAG58 on that operation, and during the rehearsals, his sling melted when he laid it over the barrel.
