FM 3-22.1Figure 2-14. M919 APFSDS-T.(1) The APFSDS-T is a fixed-type, percussion primed round that consists of asabot-encapsulated projectile crimped into a steel cartridge case. The projectile is madeof slate gray, corrosion-protected, depleted uranium. It has a screw-on steel fin withpressed-in tracer pellets; a three-piece, segmented aluminum sabot and a snap-on plasticprotective cap. The projectile sabot and protective nose-cap are black, and the slip-bandnylon obturator is white. The round has a green rubber sealant between the sabotsegments, the sabot and penetrator, and the sabot and the plastic cap.(2) This kinetic-energy round is the same as the APDS-T (M791), but with a velocityof 1,385 meters per second (plus or minus 20). The APFSDS-T round also has greatereffective range, penetration capabilities, and tracer burn time than the APDS-T.2-8. M240C 7.62-MM COAXIAL MACHINE GUNThe preferred ammunition mix for the coax is four ball and one tracer (A131). Othertypes of 7.62-mm ammunition are available. However, the four-and-one mix allows theBC and gunner to use the tracer-on-target (TOT) method of adjusting fire to achievetarget kill or suppression.

TUBE-LAUNCHED, OPTICALLY TRACKED, WIRE-GUIDED MISSILEThe developments and improvements to the TOW missile family follow thedevelopments and improvements of tank armor. The five missiles that followed the basicTOW have each improved upon the previous model. Table 2-3, page 2-20, comparesmodels. Areas of improvement include penetration, maximum range, usefulness duringadverse firing conditions, resistance to jamming, and attack profiles.a. Identification. Each TOW round has black markings and a two-inch yellow bandnear the top, plus another two-inch band near the bottom. On live rounds, the bottomband is brown; on training (inert) rounds, it is blue.b. Characteristics. TOW models still in use include the following (Figure 2-15,page 2-21).
