Direct proof of use
Pantsir-S2 was documented in the 2011 Syrian Civil War through reporting on Russia's Hmeymim airbase in Latakia. Army Recognition's Pantsir-S2 technical profile states that the variant entered Russian service in 2015, was deployed in Syria to protect Russian air-force troops at Hmeymim, and was shown there in RT Ruptly footage from February 2016.
A separate Army Recognition/TASS archive report from February 2016 described RT Ruptly footage showing Russia's Pantsir-S2 surface-to-air missile and anti-aircraft artillery weapon alongside S-400 Triumf air-defense equipment at Hmeymim. Another February 2016 Army Recognition report said the modified Pantsir systems at Hmeymim were covering S-400 long-range air-defense systems. These sources support deployment and force-protection use; they do not directly document a specific Pantsir-S2 firing or interception in Syria.

Timeline
Russia began direct air operations in Syria in September 2015, making Hmeymim the operating base for Russian airpower in support of the Syrian government. The Pantsir-S2 then appears in the public record at that base in February 2016, when footage and follow-on reporting identified the system at Hmeymim with S-400 air-defense equipment.
Future Center later described a subsequent reinforcement of Hmeymim's defenses with Pantsir-S2 and attributed Russian statements to a drone-defense role, after repeated drone attacks against the base from areas including Idlib. That later account supports the continuing force-protection role, while the February 2016 reports provide the dated S2-specific appearance.

Narrative
In Syrian Civil War service, the Pantsir-S2 was not presented as a Syrian-operated battlefield air-defense asset in the available S2-specific sources. The documented use is Russian: the system was stationed at Hmeymim airbase in Latakia as part of the defensive architecture around Russia's expeditionary air group and associated long-range air-defense equipment.
The S2 variant's role fits the Pantsir family mission of close-range air defense and force protection. Army Recognition identifies the S2 as an improved Pantsir-S1 with the same missile-gun layout, a SOTS S-band search radar, and a stated missile-range increase over the baseline S1. At Hmeymim, the system was reported with S-400 equipment, indicating a layered base-defense function rather than independent offensive use.
The strongest public S2-specific evidence supports presence, deployment, and defensive use at Hmeymim. Broader reporting on Pantsir-family interceptions in Syria often names Pantsir-S or Pantsir-S1 rather than S2, so this record does not attribute those engagements to Pantsir-S2 without variant-specific support.
