Troop

A troop is a military sub-subunit, originally a small formation of cavalry, subordinate to a squadron.

Troops is often used to refer to the other members of one's company or cause, but because of its military connotations, it conveys a particularly altruistic type of dedicated worker.

A cavalry soldier of private rank is called a "trooper" in many Commonwealth armies (abbreviated "Tpr", not to be confused with "trouper").

In the Royal Marines, a troop is the equivalent to an Army platoon; a carryover from the organisation of the British Commandos in World War II.

In the Canadian Army, a troop is the equivalent of a platoon within the armoured, artillery, engineer, and signals branches.
