FM 3-22.1c. Scale Models. Armored vehicle scale models can be used to train crews in targetacquisition, range determination, and vehicle identification. These models arethree-dimensional and are made of a hard plastic. Scale models enhance preliminarygunnery training such as range determination, gun lay, and combat vehicle identification.Table 7-1, page 4-2 is used when determining scale versus combat ranges. The localTraining Support Center (TSC) can provide scale models in 1:10, 1:30, l:35, and 1:60(Figure 4-12).Figure 4-12. Armored vehicle scale models.d. Dummy Rounds. Various dummy rounds are available to conduct training withthe M240C coax machine gun, the M242 25-mm automatic gun, and the TOW system.(1) M172 Dummy Round (7.62 mm). The M172 is a 7.62-mm cartridge minus thegunpowder and primer. It is used for nonfire training with the M240C coax machine gun.The crew should use the round with the metal tip rather than the plastic tip, because theplastic tips can bend and jam in the weapon or feed chute. The M172 dummy round canbe used to train four of the tasks that are part of the BGST. The M172 round is a Class Vitem that can be requisitioned on DA Form 581, Request for Issue and Turn-in ofAmmunition, using the information shown in Table 4-3, page 4-16:• Load the M240C coax machine gun.• Fire the M240C coax machine gun.• Apply immediate action.• Unload and clear an M240C coax machine gun.CAUTIONBecause the M172 dummy round is made of brass and canbe damaged during training, the rounds should be inspectedperiodically and replaced as needed. Continued use ofdamaged rounds or links can damage the feed chute or theweapon. Rounds and links should be checked and replacedas needed.4-13
