Do you mean in retrospect what branch suffered the most losses, either percentage wise or by number, or do you mean at the time which was the branch that those enlisting or being conscripted believed or percieved to be the most hazardous? i would imagine it was being in the submarines,but i have no statistics as yet.
It depends. Some would say that flying in a British bomber during World War Two was one of the most dangerous jobs imaginable especially for the gunners as said above. Others would say that working on board a Special Service Ship (decoy vessel) was pretty hairy. If not those, then the Field Ambulance Service was not a walk in the park either.
I`d have to agree with sddsddean, I`v just finished reading a book about the guys that defused mines and bombs during and after the war, they were the bravest of the brave
i donlt understand the previous answer, ssddsddean was suggesting that the bomb disposal experst may have served in the most hazardous branch of the British Armed services, your response to that claymore does not make sense.
I think in general it was bomber command,as a branch of the armed forces,had about 55,000 men lost,or about 25%of all uk military losses in ww2.Which were about something like 250,000.
