Commandoes yes(Not British, the cap badge is a good hint). And you are in the wrong country. One more hint: It is taken in 1944.
Thanks to everyone for all the clues. A team effort, absolutely. I would have guessed British Commandos. I'll get one up tomorrow.
This picture is reportedly from the Prokorovka sector of the Battle of Kursk. Sources: Walter S. Dunn, Silvester Stadler, Ernest Klink (Burkhalder finally transferred him to the Russian front ha), G.A. Koltunov apparently confirm Dunn's placement of the 5th Guards Tank Army - 18th, 29th and 2nd Guards Tank Corps (at last 450 tanks). I'll post a new picture in a day or so.
