Infantry Weapons

PKM/PK

The PK and lighter PKM are Soviet-designed, belt-fed 7.62x54R general-purpose machine guns used from bipods, tripods, vehicles, and improvised mounts. Their low weight for the class, non-disintegrating belt feed, quick-change barrel concept, and wide Warsaw Pact distribution make the family a common infantry fire-support weapon in the Russia-Ukraine War, where Ukrainian units continue to operate PKM-pattern guns alongside newer and foreign-supplied machine guns.

RPK/RPK-74, Squad automatic weapon / light machine gun, Infantry WeaponsInfantry WeaponsRPK/RPK-74Squad automatic weapon / light machine gunThe RPK and RPK-74 are Kalashnikov-pattern squad automatic weapons that extend the AK family with a longer, heavier barrel, bipod, and higher-capacity magazines for sustained fire by infantry sections. The 7.62 x 39 mm RPK paralleled the AKM, while the 5.45 x 39 mm RPK-74 followed the AK-74; both remain relevant in the Russia-Ukraine War because legacy Soviet and Russian stocks continue to appear in front-line small-arms holdings.
AKM, 7.62x39mm assault rifle, Infantry WeaponsInfantry WeaponsAKM7.62x39mm assault rifleThe AKM is the stamped-receiver modernization of the Soviet Kalashnikov assault rifle, chambered for 7.62x39mm and built around a long-stroke gas piston and rotating bolt. Its lower production burden, broad Warsaw Pact and licensed manufacture, and large legacy stocks keep it visible in the Russia-Ukraine War, where Ukrainian personnel have trained with AKM rifles and CAR documented AKM examples recovered from Russian-backed formations in eastern Ukraine.
AKMS, Folding-stock 7.62x39mm assault rifle, Infantry WeaponsInfantry WeaponsAKMSFolding-stock 7.62x39mm assault rifleThe AKMS is the under-folding-stock variant of the Soviet AKM assault rifle, retaining the AKM's stamped receiver, gas-operated selective-fire action, and 7.62x39mm chambering while giving airborne, vehicle-mounted, and compact-carry users a shorter folded profile. In the Russia-Ukraine War, ARES documented a specific AKMS seized by Ukrainian police from an alleged Russian saboteur, illustrating how older Kalashnikov-pattern rifles still appear alongside newer small arms.
