Direct proof of use
Direct conflict-use evidence for the T-90S/T-90SA catalog entry in the 2014 Russia-Ukraine War comes from visually documented Russian T-90S losses in Ukraine. Oryx lists Russian T-90S tanks under its Russian tank losses for the full-scale invasion, with destroyed, damaged-and-abandoned, and captured examples backed by linked photo or video evidence.
WarSpotting separately records a Russian T-90S destroyed in eastern Ukraine on 29 April 2023. The page identifies the vehicle as a T-90S, classifies it as a visually confirmed destroyed Russian tank in the Russo-Ukrainian war, and places the incident in East Ukraine.

Timeline
The open visual record currently supports the T-90S in the war's post-2022 full-scale phase rather than in the 2014-2015 Donbas phase. Oryx opened its Russian equipment-loss list on 24 February 2022 and later recorded T-90S tanks among Russian tank losses in Ukraine.
A dated incident appears in WarSpotting for 29 April 2023, when a Russian T-90S was recorded as destroyed in East Ukraine. The record was uploaded the next day and includes imagery links plus vehicle-status tags.

Battlefield role
The T-90S appears in the conflict record as a Russian main battle tank used in armored ground operations. The available public evidence does not document a separate transfer path into Russia for these vehicles; it documents fielded Russian tanks through battlefield loss and capture evidence.
The catalog keeps the variant label conservative. Oryx and WarSpotting identify the Ukraine examples as T-90S, while the parent weapon page groups T-90S and T-90SA as an export-family entry because T-90SA is a closely related export designation documented in other service contexts. The Ukraine conflict-use claim is therefore limited to Russian T-90S tanks unless a source specifically identifies a T-90SA in Ukraine.

Evidence limits
The visual-loss sources prove Russian T-90S fielding and losses in Ukraine, but they do not provide a complete order of battle or total number used. Oryx states that its list includes only vehicles and equipment with photo or video evidence and that actual destroyed-equipment totals are higher than recorded.
Captured and abandoned categories should also be read as loss-status evidence, not as proof of later operational use by another side. Oryx notes that captured equipment later lost in service with a new owner is counted only as a loss of the original operator to avoid double listings.
