Direct proof of use
The DBA-117, also cataloged as KBA-117 or KBA-17, is documented in the 2014 Russia-Ukraine War as mounted armament on Ukrainian armored-vehicle combat modules. The National Defence University of Ukraine lists the DBA-117 (AG17) in the BTR-3E armament package and states that the BTR-3 was used during the Russian-Ukrainian war. The same reference describes BTR-3DA combat modules with a KBA-117 automatic grenade launcher.
Ukraine's Ministry of Defence separately describes the BTR-4 Bucephalus as in service with the Security and Defence Forces of Ukraine and says the 20th Operational Brigade "Lubart" operates BTR-4E vehicles equipped with BM-7 Parus. In the same BTR-4 firepower section, the ministry identifies the weapon station as including a 30 mm automatic grenade launcher named KBA-17.

Timeline
The public record first supports BTR-3 and BTR-4 carrier use in the war, then identifies the DBA-117/KBA-117/KBA-17 within those carrier armament packages. For the BTR-3 family, National Defence University material states that extensive combat use before November 2015 drove hundreds of design changes, and it later identifies the BTR-3DA as a development informed by the war in eastern Ukraine. That source also lists DBA-117 or KBA-117 grenade-launcher fits for BTR-3 combat modules.
For the BTR-4 family, ArmyInform describes BTR-4E combat episodes from summer 2014 near Sloviansk through later full-scale-war actions. The Ministry of Defence's April 2026 BTR-4 overview then documents wartime BTR-4E service with the BM-7 Parus station and identifies the Parus package as carrying the KBA-17 automatic grenade launcher.

Battlefield role
In the conflict record, the DBA-117/KBA-117/KBA-17 appears as a vehicle-mounted fire-support weapon rather than as a separately documented tripod or dismounted launcher. SpetsTechnoExport describes the KBA-117 as a 30 mm automatic grenade launcher intended for use against personnel and firing points in open trenches, natural folds of terrain, and similar exposed or partially protected positions. The same product page lists BTR-style Ukrainian combat modules, including BM-3 Shturm and BM-7 Parus, as intended installations.
That role fits the carrier evidence. The BTR-3E armament lists place the launcher alongside a 30 mm automatic gun and 7.62 mm machine gun in a combat module, while the Ministry of Defence's BTR-4 overview places the KBA-17 inside the BM-7 Parus remote weapon station with a cannon, machine gun, and anti-tank guided missile capability. Public sources support mounted fielding by Ukrainian forces; they do not establish a discrete public incident in which the DBA-117/KBA-117/KBA-17 is independently identified firing apart from its carrier vehicle or weapon station.
