7-168. The commander’s fire support systems tend to focus on suppression missions to disrupt enemy forces as they are encountered and smoke missions to obscure or screen exposed friendly forces when conducting a movement to contact. The commander schedules the movements of fire support systems in synchronization with the movement of the rest of the force. Fire support systems that cannot match the cross-country mobility of ground maneuver units cause them to slow their rate of advance. In this case, if ground maneuver units do not slow down, they run the risk of outrunning their fire support. The commander synchronizes the employment of CAS to prevent the enemy from regaining balance while the commander’s ground fire support assets are repositioning. The main body updates its priority target list during a movement to contact.
