Someone else already pointed this out but I'll repeat it.
I retired from the USAF in 2001 and was stationed in Europe for ten of those years.
Although the pose is funny to look at - I am afraid those are not CHEESE EATING SURRENDER MONKEYS (AKA French Soldiers) but rather Members of Her Majesty's Army - and THEY are most definitely BAD to the bone for the most part. Be glad they are on our side - they are quite valuable allies! (Even if they do provide fodder for a funny photo.)
And yes, they can afford shooting sticks, bipods, etc. I suspect this is exercising "field expediency" however.
But still, It IS A funny photo!
