Direct proof of use
The command-post vehicle is documented in the war through visual-loss records rather than through a separate transfer or procurement trail. Oryx lists destroyed Russian command posts for both the 51U6 Kasta-2E1 surveillance radar and the 35N6 Kasta surveillance radar in its visually confirmed Russian equipment-loss catalogue for the full-scale invasion of Ukraine.
WarSpotting provides dated incident records for two of those command-post losses. One entry records a destroyed Russian command post for a 51U6 Kasta-2E1 surveillance radar in Zaporizhzhia oblast on March 1, 2026. A later entry records a destroyed Russian KamAZ 6x6 command post for a 35N6 Kasta surveillance radar near Yelyseivka in Berdiansk raion on May 4, 2026.

Timeline
The available public timeline is concentrated in 2026. WarSpotting recorded the first cited command-post incident on March 1, 2026 in Zaporizhzhia oblast, identifying the vehicle as a command post for the 51U6 Kasta-2E1 surveillance radar.
On May 4, 2026, WarSpotting recorded a second cited incident near Yelyseivka in Berdiansk raion, identifying the loss as a KamAZ 6x6-based command post for a 35N6 Kasta surveillance radar. Oryx's broader list groups these vehicles with other Russian command, communications, and radar-support losses and lists two destroyed command posts for each of the 51U6 Kasta-2E1 and 35N6 Kasta radar variants.

Operational role
The command post was a support and control element for the Kasta low-altitude radar package, not the radar antenna vehicle itself. Open Kasta-2E1 system references describe a two-vehicle system in which one truck carries the antenna and peripheral equipment while another operates as the command-post vehicle, with the external power supply on a trailer unit.
In the Russia-Ukraine war record, the vehicle's documented function is therefore air-defense support: operating with Kasta-family surveillance radars that detect and report low-altitude air targets. The cited loss records support Russian fielding and destruction of these command-post vehicles in Ukraine, but they do not establish how many Kasta command posts were deployed or whether each loss occurred during active radar operation.
