It is equipped with the fire support vehicle (FSV) and has the Striker to provide a combat laser designation capability for delivery of precision artillery or aerial-delivered munitions. The FIST assists the company commander in planning, integrating, coordinating, and executing all types of available supporting fires during tactical operations. The FIST is the commander's primary fire support coordinator and provides the commander a direct link to battalion indirect fire support systems.
