The QSZ-92 is China's standard-issue PLA/PAP sidearm — a polymer-frame, rotating-barrel pistol chambered in two distinct cartridge families, including a unique 5.8×21mm armor-defeating round, and now being supplemented by the newer QSZ-193.
The PKM is the Soviet Union's workhorse 7.62mm general-purpose machine gun — a belt-fed, open-bolt design that has armed infantry squads, vehicle mounts, and tripod emplacements across more than five decades of continuous combat from Afghanistan to Ukraine.
The L85A2 (SA80) is the British armed forces’ standard bullpup assault rifle — a 5.56×45mm NATO weapon with a short-stroke piston, 518 mm barrel, and a tumultuous early service life redeemed by a Heckler & Koch mid-life upgrade.
