The Soltam M-71 is an Israeli 155 mm/39-caliber towed howitzer developed from Soltam's earlier M-68 gun-howitzer line. It combines NATO-standard 155 mm ammunition, a split-trail carriage, horizontal sliding-block breech, compressed-air rammer, and high-speed towing gear; in Myanmar's post-2021 civil war, open reporting places M-71 guns in the captured artillery inventory from Operation 1027 rather than proving post-capture firing.
During Operation 1027, 3BHA resistance forces were reported to have seized Israeli-made Soltam Systems M-71 155 mm howitzers from junta forces; available sourcing supports capture/possession, not confirmed firing after capture.
The M-71 sits between the earlier M-68 and later Soltam 839/845 and ATHOS artillery lines. Open references treat ATHOS 2052 as visibly descended from the 839/845 branch but distinct enough to be considered a separate system, while Elbit currently markets ATHOS and ATMOS as newer 155 mm/52-caliber autonomous artillery products.

839, 839P, and 845: later Soltam refinements in the same broad towed-gun line, including auxiliary propulsion on P models.
ATHOS 2052 and ATMOS are better future catalog records than M-71 variants: ATHOS is a distinct towed 155 mm/52-caliber system, while ATMOS is Elbit's truck-mounted 155 mm/52-caliber system.

The M-71's export record is broader than the single conflict-use row on this page. Public references identify operators in Asia, Africa, Latin America, and the Middle East, while the current conflict row is limited to direct reporting of captured M-71 howitzers in Myanmar. Philippine government reporting also identifies the M-71 Soltam in Philippine Army service as one of the 155 mm platforms compatible with newly procured precision-guided munitions.
Operator inventory does not automatically create a conflict-use row. The Myanmar row is included because a conflict-specific source directly names M-71 howitzers in captured wartime materiel.
Elbit describes the M-71 as suitable for NATO-standard and other 155 mm ammunition, with range dependent on projectile, propellant, and zone.
The Philippine News Agency reported in 2025 that M-71 Soltam towed howitzers were among Philippine Army 155 mm platforms able to use acquired precision-guided munitions.

The M-71 is the 39-caliber development of the earlier Soltam M-68. Later Soltam 839, 839P, 845, and ATHOS 2052 guns are best treated as follow-on design-family context rather than simple M-71 variants.
| Variant | Configuration | Designation notes |
|---|---|---|
| Soltam M-68 | Earlier 155 mm/33-caliber predecessor | The M-68 supplied the recoil system, breech, and carriage basis; the M-71 added a longer 39-caliber barrel and compressed-air rammer. Sources: WeaponSystems.net Soltam M-71, Army Guide M-71 |
| Soltam 839 | Improved 39-caliber follow-on | Forecast International describes the 839 as a later Soltam development using the same 39-caliber ordnance as the M-71 with redesigned saddle and carriage features. |
| Soltam 839P | 839 with auxiliary propulsion unit | The P suffix marks an APU-equipped configuration with hydraulic wheel drive for limited self-movement. |
| Soltam 845 | 45-caliber follow-on | Forecast International describes the 845 as essentially an 839P fitted with 45-caliber ordnance. |
Army Guide identifies 1974 as the first-prototype point for the M-71 after development from the M-68.
