FM 3-22.1c. The BC must know the tactical situation in order to help confirm targets. He gainshis battlefield situational awareness from subordinates and higher elements. On ODSmodels that have FBCB2 and on the A3, the BC gets his battlefield situational awareness(SA) from the CTD, while the squad leader's display (SLD) provides battlefieldawareness for the Bradley crew or squad.Section III. ENGAGEMENT EXECUTIONThe crew uses the Bradley's weapon systems to engage and destroy targets with directprecision and area fires. In order for crews to take advantage of the BFV's weaponssystems to quickly lay, engage, and destroy threat targets, they must be experts in the useof target-engagement methods and techniques.6-11. METHODSOnce he acquires and discriminates a target, the BC must determine the method ofengagement. Two engagement methods apply to the 25-mm and to the coaxialmachine gun--battlesight gunnery and precision gunnery. Each has its own firecommands (Section V). The Bradley ODS and A3 gunner uses the ELRF to determinerange, then the BC gives a precision fire command. He selects the method of engagementbased on his estimate of the situation.NOTE:Battlesight and precision methods do not apply to the TOW system, becausethe TOW's ammunition has fixed ranges.a. Battlesight Gunnery. For the Bradley without a ELRF or whose ELRF fails,battlesight gunnery offers the fastest way to engage a target. It relies on preselectedammunition and range settings. This set of "preindexed" information is calledthe battlecarry. This battlecarry allows the gunner or BC to aim, shoot, and burst ontarget (if necessary). This relieves the BC from having to identify and the gunner fromhaving to select either the ammunition or the range. While planning fire and selectingbattlecarry, the BC considers several factors. First, he selects ammunition for the mostlikely enemy target. Second, he selects the most likely engagement distances and rangesettings for those targets. The BC has two options when selecting battlecarry--ballisticand extended. Each is based on target height, ammunition characteristics, capabilities,and expected engagement range bands.(1) Ballistic Battlecarry. The BC uses the ballistic firing tables (FT 25-A-2) to obtainthe necessary ammunition information for his selected battlecarry target. From thesefiring tables, the BC can obtain the height of the expected target. Then, regardless of thetarget's motion, the gunner aims at half its height. The BC chooses a range that will keepthe highest path of the selected ammunition from passing over the target. If, for example,the expected target is a BMP 2, the BC will use the M791 ammunition. The targetmeasures 2.45 meters high. He has the gunner aim at half that height, or 1.225 meters.Maximum ordinate is the highest measurement the round will travel above theline of sight. When he checks the maximum ordinate column in the firingtable (FT 25-A-2), the BC notes that 1.1 is the largest number that does not exceed 1.2(rounded down from 1.225 meters). Reading right or left to the range column, he sees thata range of 1,200 meters corresponds to a maximum ordinate of 1.1. He instructs the6-27
