FM 3-22.1(a) High-explosive 25-mm rounds arm 10 meters from the gun and explodeon contact.(b) Because the APDS-T round discards plastic sabots to the front of the gun, the25-mm has a 60-degree safety fan. This fan extends 30 degrees to each side of the guntargetline and out 100 meters to the front of the gun (Figure E-6). Thus, when the gunneror BC fires armor-piercing rounds, exposed soldiers must remain to the rear of the 25-mm’s muzzle (outside the 60-degree arc) or at least 100 meters from the muzzle blast.(c) To prevent fratricide, BFV-equipped units must develop SOPs to help Bradleycrews identify friendly dismounted soldiers. They can mark LBE, helmets, or uniformswith reverse-polarity tape, thermal or chemical lights, and so on. However, use of suchmeasures must be weighed against enemy's thermal capabilities. For example, theM2A3's IBAS allows the viewer to see helmet bands and LBEs marked with reversepolarity tape.Figure E-6. Safety fan for 25-mm gun.g. Isolation of a Building. To isolate a building, the BFVs take an overwatchposition (Figure E-7). They fire the 25-mm gun and 7.62-mm coax machine gun.
