Bri is correct. Eisenhower at Prague Airport 1945. After Warmtoast stated:-
Yanks, Brits and Russians and possibly some French in there somwhere so I guess it's 4-Power Berlin and with the British troops forming the guard of honour, my guess is RAF Gatow.
I thought the battledress and webbing was British but the way the berets were being worn certainly was not the way the British Army wore their berets. "The badge goes over the left eye" not half way round the head.
