Chapter 4 4-10 ATP 3-09.30 28 September 2017 MESSAGE TO OBSERVER 4-68. After the FDC receives the call for fire, it determines if and how to attack the target. The FDC announces that decision to the observer in the form of a message to observer (MTO). The observer will acknowledge the MTO by reading back in entirety, and if conducting a grid mission may include, BREAK, DIRECTION (observer- target direction) at the end. The MTO consists of the four items discussed below. UNIT(S) TO FIRE 4-69. The battery (or batteries) that will fire the mission is (are) announced. If the battalion is firing in effect with one battery adjusting, the FDC designates the fire for effect unit (battalion) and the adjusting unit by using their specific call sign. Example The battalion call sign is Thunder. Battery A is Apache. Battery A will adjust, and battalion will fire for effect. The MTO would be THUNDER, APACHE. CHANGE TO CALL FOR FIRE 4-70. Announce any change to what the observer requested in the call for fire. Example The observer request ICM in effect and the fire direction officer decides to fire variable time (VT) fuze in effect. The MTO begins T, G, VT IN EFFECT or alternatively THUNDER, APACHE, VT IN EFFECT. NUMBER OF ROUNDS 4-71. Announce the number of rounds per tube in fire for effect. Note. If the firing unit is MLRS and HIMARS the FDC will specify only the total number of rounds to be fired. Example The MTO thus far is T, G, VT IN EFFECT, 4 ROUNDS or alternatively THUNDER, APACHE, VT IN EFFECT, 4 ROUNDS. TARGET NUMBER 4-72. Assign a target number to each mission to facilitate processing of subsequent corrections.
