About detachment

A detachment is a military unit. It can either be detached from a larger unit for a specific function or be a permanent unit smaller than a battalion. The term is often used to refer to a unit that is assigned to a different base from the parent unit. An example is the United States Army's 1st Special Forces Operational Detachment-Delta (Airborne) (SFOD-D), commonly known as Delta Force by the general public.
