I remember my ww2 vet RN PO telling me about an RN medic’s job after being bombed by the Luftwaffe. The medic was tasked with the awful job of recovering a sailors’s body from under the forecastle of his destroyer...probably off Crete early 40s.
They do everything. Some RN Medics will complete the All Arms Commando Course and will serve alongside Royal Marine Units or UK Special Forces Medical Group.
