Direct proof of use
The 122 mm M-30 howitzer appears in the Syrian Civil War record through multiple open-source identifications. Oryx reported in June 2017 that Russian rearmament deliveries to Syrian Arab Army-linked 5th Corps forces included World War II-era 122 mm M-30 howitzers, placing the type in pro-government service during the war.
Oryx later documented one 122 mm M-30 howitzer in its inventory of YPG heavy equipment in northern Syria. A separate Oryx loss list for the Battle of Conoco Fields records one 122 mm M-30 howitzer destroyed among Wagner/Syrian government forces, with the list limited to equipment for which photo or video evidence was available.

Timeline
The dated public evidence starts with Russian support to the Syrian government's 5th Corps rearmament effort in 2017. Oryx described the deliveries as part of a Russian-backed effort to rebuild and equip government-aligned forces after years of war.
The most specific combat-loss event is the February 7-8, 2018 Battle of Conoco Fields near Khasham in Deir ez-Zor. U.S. official accounts describe an attack by pro-regime forces on Syrian Democratic Forces positions east of the Euphrates River deconfliction line, while later reporting and research identify Wagner-linked personnel among the attacking pro-government forces. Oryx's equipment-loss list for that battle identifies a destroyed M-30 howitzer on the Wagner/Syrian government side.

Battlefield role
In Syrian government and allied service, the M-30's documented role was legacy towed tube-artillery fire support. The 2017 delivery reporting describes the guns as part of a broader package of older Russian-supplied vehicles and weapons intended for Syrian Arab Army-linked forces operating against Islamic State positions and other armed factions.
The YPG evidence is narrower. Oryx lists a single 122 mm M-30 howitzer under limited-quantity towed artillery in northern Syria, alongside other scarce heavy weapons. That source supports possession or fielding by the YPG/SDF side, but it does not establish a detailed firing history or identify a specific engagement in which the YPG fired the gun.

Evidence limits
The strongest M-30-specific claims are the Russian delivery report, the YPG inventory entry, and the visually documented destroyed gun at Conoco Fields. Official U.S. sources support the broader Conoco battle context, including pro-regime artillery and mortar support during the attack, but they do not identify the M-30 by model.
The sources used here do not support a complete count of M-30 howitzers in Syria, a reliable rate of use, or attribution of particular shelling incidents to the M-30 rather than to Syria's wider mix of 122 mm and larger artillery systems.
