GT - you make a fair point as valid as any other. No worries. Perhaps the following comment I just puled off the ARRSE thread says it all:
'For the first time ever I was impressed by the attitude and demeanor of RAF pilots. They came across really well... '
So I think you are right to mention the potential PC issue (after all, it got your heckles up) but it seems that no harm was done regarding disrespect to soldiers, which is appropriate as I know than none was intended.
