Encyclopaedic reference on the machine-gun families employed in Ukraine. Public doctrinal information only: categories, role, calibres, variants, distribution. No operational, firing, barrel-management, tactical handling or maintenance instruction.
Categories and role
Machine guns are classified by role and calibre. The light machine gun (LMG) operates at squad level in intermediate calibre (5.56/5.45). The general-purpose machine gun (GPMG) operates at squad/section level in full-power calibre (7.62×51 / 7.62×54R). The heavy machine gun (HMG) operates in 12.7 mm calibre, typically from fixed or vehicle mounts, for long-range anti-personnel support, anti-light-vehicle and low-altitude air-defence roles.
General characteristics
- LMG (5.56/5.45): 7-8.5 kg, belt or magazine, base-of-fire role at squad level
- GPMG (7.62×51 / 7.62×54R): 9-12 kg, belt, quick-change barrel, medium support role
- HMG (12.7): 25-40 kg + tripod, effective range up to 1800 m anti-personnel, 2000 m anti-vehicle
- AGL (automatic grenade launcher): 40×53 (USA) or 30×29 (RUS), HE/HEDP grenade bursts
- Feed: disintegrating belt (NATO) or non-disintegrating (post-Soviet)
- Rate of fire: 700-1300 rpm typical, MG3 up to 1300 rpm
- Mount: integral bipod, separate tripod for sustained role, vehicle mount

| PKM / PKP Pecheneg | 7.62×54R — GPMG | 1969 / 1999 | GPMG sovietica/russa, standard post-sovietico. Vedi scheda dedicata PKM. |
| HK MG3 / Rheinmetall | 7.62×51 NATO — GPMG | 1959 | Erede tedesca della MG42, alta cadenza (~1100-1300 rpm), ancora in dotazione. |
| M2 Browning | 12.7×99 NATO (.50 BMG) — HMG | 1933 | Mitragliatrice pesante più longeva al mondo, montaggio veicolare e treppiede M3. |
| DShK / DShKM | 12.7×108 — HMG | 1938 / 1946 | HMG sovietica, montaggio veicolare, anti-aerea e anti-personale a distanza estesa. |
| NSV / Kord | 12.7×108 — HMG | 1971 / 1998 | Sostituti della DShK in unità russe moderne, Kord retroffittabile su torrette. |
| MK 19 / AGS-17 Plamya | 40×53 / 30×29 — AGL | 1968 / 1971 | Lanciagranate automatici, raffiche di granate HE/HEDP a 1.5-2.2 km. |
Calibre vs tactical role
Intermediate calibre (5.56/5.45) — light infantry squad, rapid deployment, practical range to 600 m. Full-power (7.62×51/7.62×54R) — platoon/section support, practical range 800-1200 m, higher weight and logistics. 12.7 mm — heavy support, anti-materiel, low-altitude anti-air, range 1500-2000 m. 40×53/30×29 AGL — area saturation, indirect at 1.5-2.2 km, against exposed infantry.
Distribution in Ukraine
Ukrainian forces field PKM/PKMS as principal GPMG, FN MAG (M240B), M249 received through aid, legacy RPK/RPK-74, and Browning M2 on vehicles and fixed positions. Russian forces use PKM, Pecheneg, RPK-74, NSV/Kord 12.7, DShK in irregular/LDPR units, AGS-17 Plamya 30 mm. GPMG fire on the trench line is a central and continuous tool of current positional warfare.
Advantages (doctrinal)
- Sustainable volume of fire — higher than any individual weapon
- Area suppression capability, not just point engagement
- Quick-change barrel (GPMG/HMG) supports sustained rate
- HMG bridges the gap between machine gun and light cannon
- AGL produces saturation effect to 2 km
Limits (doctrinal)
- Weight and logistics of sustained ammunition
- Barrel overheating on prolonged bursts (management required)
- Launch signature (smoke, sound) — priority enemy target
- Fixed HMG is identifiable target from ISR drone — short trench life
- Operator exposed in traditional frontal emplacement
