Could anyone help me with the badges on the uniform of the chap on the right of this photo? He is my Uncle Chris and family legend always had it (think my dad perpetuated the myth) that Uncle Chris was a rear gunner on Lancaster Bombers during WW2, however, I've got his discharge papers which give his rank as LAC (Leading Aircraft Man)? and his trade as ACH/GD (Aircraft Handler/General Duties)? The papers also say he is 'unfit for active service'. I know he was in Egypt during the war, so did go overseas.
Many thanks in advance!
All the best
