squaddie
What does squaddie mean?
A British Army rank-and-file soldier — the generic word for a serving squaddie, whatever cap badge. Used by squaddies about themselves and by the British public in general. Carries the whole bundle: lads on the piss in garrison towns, professionalism on tour, dark humor about all of it.
Origin
British forces slang from the mid-20th century — from 'squad,' the basic unit of soldiers drilled together. Originally meant a recruit; broadened to mean any ordinary serving soldier.
