Throughout history I would guess the soldier’s response to the dark terror of war has been a sense of humour, often even in the grimmest of situations. One of the most famous cartoons ever drawn was created by Bruce Bairnsfather, a British artist who fought in the trenches on the Western Front. As an antidote to the “patriotic” sketches made by the staff artists in the London magazines, who had no experience of war, Bairnsfather’s observations of everyday life in the trenches became very popular with the soldiers themselves and this one, with it’s grim humour became the stuff of legend.
The descendants of those WW1 “old sweats” are now British squaddies serving in Afghanistan with the ever present shadow of the hidden bomb and the silent sniper. So, to blunt the edge of concern about what the next hours might bring, they use humour to alleviate the daily routine.
BTW the soldiers in the vid are ordinary squaddies, despite the youtube title. Although no doubt the SAS have their own outbursts of dark humour these, like their military activities, would be shrouded in secrecy – so, these men are not SAS..but, of course, they could well be…
