tom
What does tom mean?
A British Army private soldier — especially in the Parachute Regiment and infantry, where 'the Toms' means the lads, the rank and file. Counterpart to 'Rupert' for officers. Used inside the regiment with pride: the Toms are the ones who actually do the fighting.
Origin
From 'Tommy Atkins,' the generic name used on sample British Army paperwork from the early 1800s — became the universal nickname for the British private soldier through the Victorian era, WWI, and beyond. 'Tom' is the shortened modern Para and infantry usage.
