Oh yes, the Top Secret "Hotel Foxtrot" exercise names.... which everyone for miles around knew actually stood for "Harrier Force".
Ours were were "Spring, Summer, Autumn and Frozen Tiger". Saw some lovely farmyards and a few 7 by 5 tents with no poles, pegs or guy ropes.
And no fridge..... unlike the Harrier "home from home", tented city sites.
