FM 3-22.1(5) If the Bradley and target are moving parallel to each other, in the same direction,and at the same speed, the gunner need not apply any lead. The vehicles' matchingmovement eliminates the need.(6) If the Bradley and target are moving parallel but in opposite directions, the gunnerdoubles the initial lead (Figure 6-31). With HE ammunition, this can cause the gunner torun out of lead lines. If this happens, he changes to AP ammunition for thatspecific situation.Figure 6-31. Far lead applied when a target and a Bradley are parallel andmoving in opposite directions.6-13. DIRECT-FIRE ADJUSTMENTThe crew has various ways to adjust direct fire, including burst-on-target and traceron-target.a. Burst on Target. Burst on target, the fastest method of adjustment, moves thestrike of the round from the ground onto the target.(1) After the gunner has made his initial reticle lay on the target and fired, he appliesBOT by--(a) Concentrating on the target, noting the point on the sight reticle where the roundappears as it hits or misses the target.(b) Announcing his observation and BOT.(c) Immediately adjusting the reticle aiming point based on his observation, to bringthe next round or burst on target. He must adjust quickly and accurately. This makesadditional adjustments or subsequent fire commands unnecessary.(d) Announcing "On the way" and firing a burst of three to five rounds.(e) Continuing to fire, adjusting each burst onto center mass until one destroys thetarget or the BC commands CEASE FIRE.(2) When the gunner applies BOT, the BC can observe the first round fired and thesubsequent burst of fire for deflection and range.(3) Accuracy of the BOT method of adjustment depends on the gunner's ability tomaintain correct sight pictures and to make precise observations. To engage movingtargets accurately using BOT, the gunner must track continuously—before and duringthe engagement.b. Tracer on Target. TOT is similar to BOT. As the name implies, the gunner orBC fires the 25-mm or coax machine gun. The firer adjusts the strike of the rounds ontothe target area based on the tracers.c. Adjustment Techniques. The gunner and BC can announce adjustments usingany of the following methods:(1) Target-Form Adjustment. Target form is the simplest method of adjustment. Oneform is the visible height or width of the target. Range adjustments (up or down) refer to6-32
