Group photo of men from 6th Airborne Division in Palestine.

Do we know who this group were or where from or any further detail?

My grandfather is in the back row, second one in from the right. His name was William David Humphreys. We know he was a sergeant as there is another one of him in the sergeants mess in Palestine. My mum's seems to think he was an RSM but I can't corroborate that

I would recommend you obtain a copy of his service records, which will list, among other items of interest, his rank.
