Direct proof of use
The 1V119 Reostat appears in the conflict record through Ukrainian Donbas-era reporting, OSCE monitoring, and later visual-loss documentation from the full-scale invasion. Censor.NET's account of the August 2014 Shakhtyorsk fighting describes the Ukrainian 25th Airborne Brigade's first battalion group as including three 2S9 Nona vehicles and two 1V119 Reostats, and labels a photographed 1V119 as belonging to that brigade group.
The OSCE Special Monitoring Mission later recorded a BTR-D 1V119 Reostat in a government-controlled area near Novoselivka Druha on 4 December 2017. That observation places the artillery command vehicle in the Donbas security-zone environment alongside nearby 2S9 Nona self-propelled mortars reported in the same daily report.
Russian use is documented in the full-scale phase by captured-equipment and loss records. WarSpotting records a 1V119 Reostat captured from Russian VDV forces near Mykolaiv on 3 March 2022, Oryx lists visually documented Russian 1V119 artillery fire direction vehicle losses, and Defense Express and Army Recognition reported a Russian 1V119 captured in Kherson Oblast in November 2022.

Operational role
The Reostat's conflict role was artillery support rather than direct fire. Army Recognition describes the 1V119 as an airborne artillery battalion fire-direction vehicle used with 2S9 Nona 120 mm self-propelled mortar carriers, while Defense Express describes it as a vehicle for controlling Nona battery fire and notes its communications, navigation, and fire-control equipment.
That role explains why the documented sightings cluster around airborne artillery units and Nona-related formations. In the 2014 Shakhtyorsk account, the 1V119s are listed in the same first battalion group as three Nonas; in the 2017 OSCE report, the Reostat was observed near Novoselivka Druha on the same date that an SMM UAV spotted two 2S9 Nona-S self-propelled mortars near the settlement.

Captured and lost vehicles
Capture records show changes of possession but should not be read as automatic proof of later operational reuse. WarSpotting marks the 3 March 2022 Mykolaiv vehicle as Russia VDV to Ukraine, while Defense Express and Army Recognition reported a Russian 1V119 abandoned and captured in Kherson Oblast as Russian forces left the west bank of Kherson Oblast.
Oryx's Russian equipment-loss list records multiple visually documented 1V119 artillery fire direction vehicles as destroyed, captured, or damaged and captured during the full-scale invasion. Together with the WarSpotting and November 2022 Kherson reports, those records support Russian fielding and Ukrainian capture of the type in the conflict, while the older Shakhtyorsk and OSCE evidence supports Ukrainian operation of Ukrainian 1V119s before 2022.
