Who is in charge of the FIST and is the principal fire support advisor to the commander when attached to or supporting a company or troop?

The Company/Troop Fire Support Officer (FSO) is responsible for leading the Fire Support Team (FIST) and serves as the principal fire support advisor to the commander when attached to or supporting a company or troop. This role is crucial as the FSO coordinates and integrates fire support efforts to enhance the effectiveness of the unit’s operations.

The FSO’s training and knowledge enable them to provide critical information on the capabilities and limitations of various fire support systems, advise the commander on the best methods to use indirect fire to achieve tactical objectives, and ensure that all fire support actions are synchronized with maneuver operations. By being directly embedded with the company or troop, the FSO can quickly communicate and adjust fire support plans based on the commander’s intent and the evolving battlefield situation.

In contrast, the other roles such as the Battalion/Squadron FSO or FSNCO are focused at higher command levels and do not fulfill the same direct advisory and coordination function at the company or troop level. The FSNCO typically handles more administrative and logistical responsibilities, further distinguishing the FSO’s role as the primary support advisor and team leader within the FIST.
