Mowgli - an excellent post. The 'real' tents at Incirlik are still in use and some people have been going there for 10 years now due to the in-theatre mission creep. But, as you rightly stated, they are of sound construction, properly sited and the guys at least have hot water! Messing facilities are also entirely satis - and anyone can get a decent night's sleep.
But the situation in Onan is totally different - and is a festering sore which needs urgent treatment.
Incidentally, now that there's more space in the BFOT, I trust that every visiting senior officer is staying there....
