Short-arm inspection

The term "short-arm inspection" is a military euphemism referring to the routine medical inspection of male soldiers' penises for signs of sexually-transmitted diseases and other medical problems.
The precise origin of the term is uncertain; however, American and Australian troops are known to have used the term during the First World War.

Examples

The practice within the Imperial Japanese Army during World War II was described by an anonymous American soldier, who had been forced to work as a truck driver while held as a prisoner of war, and who came into daily close contact with Japanese soldiers.

In literature

The practice of short-arm inspection was described in Earle Birney's novel Turvey, a comic account of Canadian soldiers during World War II.

After the ordained blanket line-ups and personnel quickies, the new arrivals were given a short-arm inspection. Although this was already Turvey's fourth since enlistment, it was the first since hospitalization and he awaited his turn with some apprehension.
The twenty silent soldiers were paraded by a silent corporal into a small room smelling of lysol. They shuffled in a single line past the RAP Sergeant... The sergeant had the reputation of being the fastest and merriest short-arm inspector in the Canadian Army.
