FM 3-22.1the height of the target; azimuth adjustments refer to the target's width. They can usetarget form adjustment with the ISU, IBAS, or the auxiliary sights. They can add theword "form" after the announced change, or they may let the change stand alone. If"target form" is the unit's standard adjustment technique (IAW unit SOP). Thecommander always gives changes in full- or half-form increments.(2) Mil Change. This method is simple and accurate at all ranges, but the gunnermust know his reticle's mil measurements. He gives mil changes whenever he uses anonballistic reticle in the ISU or IBAS.(3) Meter. Because the auxiliary sight is marked in meters, the gunner uses metersrather than mils. He must know how to read both of the ballistic reticles in his sight (APand HE). Though he can use this technique with the ISU, converting meters to mils cancause confusion.6-14. 25-MM-POINT TARGETSLikely point targets on the battlefield include unarmored vehicles, lightly armoredvehicles, bunkers, RPG teams, and helicopters. When firing 25-mm point targetengagements, the gunner first fires a sensing round (two if the ammunition has changed).He announces his observation and adjusts rounds by BOT (Figure 6-32). Then, he firesthree- to five-round bursts on the target. He continues firing bursts until he destroys thetarget or the BC commands CEASE FIRE.Figure 6-32. Burst on target against point target.6-15. FIRE-CONTROL SUBSYSTEMThe FCS controls the Bradley A3's weapons system. Fire-control software (FCSW)provides the main link between the system and the CIV, IBAS, ballistic solution software(BSS), and TDS.a. The FCS takes--(1) Target range from the LRF.(2) Barometric pressure and temperature data from the environmentalparameters screen.(3) Ammunition and gun type from the system control box (SCB).b. Using these figures, the FCS computes the correct angles needed to kill the target.With this information--(1) The crew independently searches, tracks, and hands-off targets for engagement.(2) The crew tracks targets automatically.(3) The commander overrides the gunner.6-33
