In reply to Reinhardt (good to see you back on the forum), he did carry a PSK as well. It was the BCB go-pack and some of the gear he listed was from that kit. This means that he did not infact list everything he carried.
I would suspect that this individual is in better physical condition than the average office worker in North America
Oh yes, the SAS are the creme de la creme of the British armed forces (Although i'm sure they're nothing compared to in the US, because all your forces are the special forces <img src="images/graemlins/grin.gif" alt="" /> <img src="images/graemlins/wink.gif" alt="" />).
did he say if that was his standard equipment or mission specific? I know he was talking about adapting what he carried depending on the mission, especially regarding MRE's.
The belt kit is pretty standard as it is mostly survival and escape and evasion gear so is therefore not mission specific. However lots of the rest of the kit was. The mission they were doing was an offensive OP (i.e. they were setting up an observation post but would react with force if needs by, in this example, a renegade general) this means that a lot of the gear they carried was specialist. e.g. spotting and night vision scopes, entrenching tools scrim and camoflage, chicken wire to hold camoflage and most importantly a A1 sniper rifle.
Hope this is all helpful.
