It really isn't a BOB. It's more like the intermediate step between your ruck (which you might have to leave behind for some reason) and your pocket kit (which you should have on you at all times, and if captured, do your damnest to keep it from being found). Remember, Wiseman wrote from the perspective of military survival, evasion, resistance and escape. SERE in Bohicastan is a lot different than what most of us will encounter (unless you live west of the San Andreas and it's having a bad day).
What he showed was based on what you'd have on your combat harness along with your ammunition, knife, compass, canteen and first aid kit. Is you are going by SAS SOP, that webbing, your boots and your weapon are your pillow at night, and never more than ten feet from you during the day. Everything else is not part of you escape and evade load. The belt kit was designed to keep you alive until you see friendlies, and then get their attention.
I'm not knocking his book, I'm just saying keep in mind his perspective on things is a lot different from most of us will ever experince. It isn't a BOB, it is a SERE pouch. But not everything in it translate well to a non-military audience.
Unless it's been added in the latest edition, Wiseman never talks about bugging out, nor does he do so in the Urban Survival Guide (not very good, if you dont' have it, don't bother- most of it is stuff that I would think anyone who doesn't have a date with Darwin would know other than the first aid and "what to do in case of becoming a hostage"). Do the Brits not bug out?
