FM 3-22.1a. The 25-mm gun is effective against slow-moving, fixed-wing aircraft andhelicopters (Figures 6-48 and 6-49, page 6-46). When using the ADR sight, the gunnerindexes 1,800 meters. He can use APDS-T, APFSDS-T, or HEI-T ammunition. Tosustain the volume of fire and kill the target, he fires a continuous burst of 20 to 25rounds (high rate), using TOT to adjust rounds on target. The APDS-T and APFSDS-Trounds have higher probabilities of hitting the target than does the HEI-T round.However, its greater dispersion factor gives the HEI-T round a higher probability of kill.For helicopter targets--(1) At ranges beyond 1,200 meters, the APDS-T is the most effective round.(2) At ranges within 1,200 meters, the HEI-T is the most effective round.(3) The ADR applies only for use on frontal targets.Figure 6-47A.
