On this forum, people exchange facts (occasionally) and opinions. Express an opinion is precisely what green_king did and, although it may have displeased you, he should not be belittled nor subject to that patronising waggy finger cartoon thing.
Pot to kettle over.
Referring to folk doing their bit as REMFs is far more belittling. There are very many at KAF who, during their tour, spend quite a bit of time out on the ground and in harm's way - and not just the RAF Regt or RBG(S). Sweeping generalisations such as those made by Green King are divisive and don't help.
Perhaps the waggy finger thing was slightly misjudged.
