Sub-subunit or sub-sub-unit is a subordinated element below platoon level of company sized units or sub-units which normally might not be separately identified in authorization documents by name, number, or letter. Fire and maneuver teams, fireteams, squads, crews, sections and patrols are typically sub-subunits.
