Troop Commanders are responsible for a large number of personnel in the Organisational Chain of Command (ORGCOC). Supported by a senior NCO known as a Troop Sergeant, the Troop Commander supports the Troops Section Commanders with the administration of the Troop, addressing the escalation of reports from section and troop level to command level, as well as focusing on the development of leadership - both of the troops NCOs and it regulars.
As Troop Commander, they take full responsibility for the troop - handling the entry and exit of personnel from the troop, promotions and selection boards, conduct reviews, policy violations and medal issue. The troop commander has the final say within the troop. As a (O-1) 2nd Lieutenant office, the Troop Commander is a Commissioned Officer and reports directly either to a Company Commander (CC), or Commanding Officer (TFCO) - depending on the size of the task-force.
As an Officer, Troop Commanders have a number of other responsibilities which can be found in administrative SOP. Typical combat duties of Troop Commanders are Squad Leaders, Platoon Commanders, Company Commanders or in some cases, Mission Support.
