Never thought I'd find myself sticking up for the FC world, but as has been pointed out, to even get to Waddo they have to do upwards of 2yrs training then several tours and then they only get there if judged good enough to go - well that's the theory anyway.
Who cares what they wear, whether it's a badge or a brevet, they do a hard job well.
However if you really want to moan about un-earned brevets -
Whatabout the Int Corps getting a brevet for an 8 week attendance course on ASTOR. I know a few of them and they are chuffed to bits to get something aircrew work years for - they now think getting a brevet is easy. And they think that there will eventually be an Army Lt Col running 5 Sqn.
Comments, suggestions, explosions ........ How's that for throwing a hand grenade into the converation!!!
