The Dozor-B is a Ukrainian 4x4 light armored personnel carrier developed by Kharkiv Morozov Machine Building Design Bureau for protected patrol, reconnaissance, command, medical, and troop-transport roles. Its public record now divides between a small Ukrainian Dozor-B run and the Polish-built Oncilla derivative family, including Ukrainian wartime Oncilla deliveries, battlefield use, specialist Oncilla variants, and the Oncilla-Shturm configuration approved by Ukraine's Ministry of Defence in 2024.
Ukrainian Dozor-B use is directly supported by the 2016 batch of 10 vehicles accepted for Ukrainian military use; later evidence documents upgraded Dozor-B vehicles for Defence Intelligence, Oncilla derivative deliveries and battlefield use by Ukrainian units, and the 2024 Oncilla-Shturm approval for Ukrainian Armed Forces operation.
Role detailsThe Oncilla branch gives the Dozor-B family a distinct wartime production and service path. MISTA identifies serial Oncilla production in Poland and says more than 200 4x4 Oncilla vehicles had been delivered for Ukrainian Armed Forces needs and checked during combat tasks in the war with Russia. 2025 reporting from Euromaidan Press, citing Ukrinform and MISTA development comments, describes continued adaptation from Ukrainian soldier feedback and additional planned deliveries.
Licensed or redesigned Dozor-B derivative associated with Polish MISTA production and Ukrainian Beryl technical partnership.
Defense Express and MISTA describe Ukrainian battlefield use; Defence Blog reported a Defence Intelligence Oncilla delivery and cited 30 vehicles already in service in 2023.
MoD-approved 2024 configuration with remote heavy-machine-gun weapon station and protected mobility features for Ukrainian forces.
MISTA lists medical, electronic-warfare, artillery command, and assault configurations, while Beryl advertises reconnaissance, command, medical, police, and anti-tank adaptations.

The Dozor-B is built around a front powerpack, central crew positions, and a rear troop compartment rather than a tracked infantry-fighting-vehicle layout. Its public specification emphasizes protected mobility and patrol use: armor protection against 7.62 mm armor-piercing fire, limited mine protection under the floor, firing ports, day and night observation equipment, central tire inflation, a winch, and an NBC filtering and ventilation system.
Three crew positions plus eight dismounts in the commonly cited APC layout.
Steel hull protection against 7.62 mm armor-piercing fire, with mine protection described as 0.5 kg TNT equivalent under the floor.
4x4 chassis, Deutz or Iveco diesel options, central tire inflation, and roughly 100 km/h road speed in open specifications.

Open sources use Dozor-B for the Ukrainian armored 4x4 family and Oncilla for the Polish licensed derivative; later Ukrainian reporting describes upgraded Dozor-B vehicles that differ from early production examples.

| Oncilla-Shturm | Ukrainian-approved assault configuration | Ukraine's Ministry of Defence said the Oncilla-Shturm armored personnel carrier was codified and adopted in November 2024, with three crew, six dismounts, automatic transmission, remote weapon station, and several possible configurations. MISTA describes the assault version as an Oncilla-based configuration with increased firepower from a TAVRIA-14.5/7.62 combat module.

Army Recognition says Poland began producing the Oncilla licensed version in 2013; later MISTA and Ukrainian reporting tie the derivative back to the Dozor-B design and to Polish serial production.

Public reporting presents Dozor-B as a Ukrainian design with a constrained domestic production history and a more durable derivative path through the Polish Oncilla. The Ukrainian batch accepted in 2016 remained small in open reporting, while Oncilla deliveries later gave Ukraine another route to vehicles based on the same design lineage. The 2023 Defence Intelligence delivery shows that Kharkiv-produced upgraded Dozor-B vehicles also reappeared during the full-scale phase of the war.
