I enjoyed my time posted to a couple of RAF stations. I do look out for the crabs every now and then, and post on PPruNe. Their caption competition can be quite amusing.
That said, the crabs are such a politically motivated, in-fighting bunch of introverts, so they've shot themselves in the foot I don't know how many times. That gets a bit old, so I'm no crab-o-phile, but I do wish we had a decent air force.
