Just a question. Why carry one of them big and heavy right angles torches? I was given one of them myself from an ex SAS person - among a whole lot of other stuff - and found them obsolete compared to what is available today.
also this guy did he carry a PSK aswell? I doubt it looking at the list but i think it would have been a beter option in IMHO. Reason: you've got everything in one place - more control but of course more risk.

A good idea though is the compass(es) in addition to the GPS.

Just my 2 cents
