The guy presenting it is a desert explorer called
Micheal Asher, whom I understand is
ex-SAS himself.....
Of course, the local
Iraqi's could be telling
fibs
, and I understand there was a govt
minder 
accompaning the film crew.......
But they did produce
artifacts from the abandoned bergens, such as clips of ammo. Asher said they could only by UK issue....
I'm not ex-mil (apart from a short spell in the TA
), so I can't really comment on the
soldiering stuff.....
But Asher (who looked a very
fit bloke to me) was
knackered carrying B20's load for a
few kilometers, and said he couldn't possibly have managed
20.......
Finally, the most telling point to me was the real
anger that Asher and the ex-RSM had towards these men, that they had let down the
regiment........
