Reuters and RFE/RL documented a Ukrainian AHS Krab unit in the Donetsk region in August 2022, describing the NATO-compatible 155 mm tracked howitzer as deployed by Ukraine against Russian targets near Donetsk. The same photo report identified Ukrainian soldiers driving a Krab after engaging Russian forces on August 23, 2022, and noted Poland's donation of Krab howitzers to Ukraine.
A separate RFE/RL video feature published later that month showed a Ukrainian crew operating a Polish-built Krab after previously using a Soviet-era Msta-S. Together, the reporting supports both Ukrainian operation of the system and battlefield employment during the full-scale phase of the war.

Timeline
Open reporting places the first public transfer and employment milestones in late May and June 2022. RFE/RL reported on May 29, 2022 that Poland was giving Ukraine 18 AHS Krab self-propelled howitzers and training about 100 Ukrainian artillerymen to operate them. Defence24, citing Ukrainian reporting, then described Krab howitzers as introduced into the fighting around Sievierodonetsk in June 2022.
By early June 2022, Polish Prime Minister Mateusz Morawiecki had announced a sale of additional Krab howitzers to Ukraine, with Defense News reporting that the weapons were intended to strengthen Ukrainian artillery and could engage targets at up to 40 km according to manufacturer data. In November 2022, Defence24 reported Ukrainian Krab use with M982 Excalibur precision-guided 155 mm ammunition.

Narrative
The Krab entered Ukrainian service as part of the wider shift from Soviet-standard artillery toward Western 155 mm systems after Russia's February 2022 full-scale invasion. It gave Ukrainian artillery units a tracked, armored, NATO-caliber self-propelled gun with a 52-caliber main armament, compatible with standard 155 mm ammunition and later reported precision-guided rounds.
Its documented role was battlefield artillery fire support rather than a single isolated strike capability. Reports tied the system to eastern front fighting, including Sievierodonetsk and Donetsk-region activity, and to Ukraine's broader need for longer-range artillery able to counter Russian forces while displacing between missions. The Defense News account of the Polish sale framed the additional guns as intended for Ukraine's eastern battlefield, while Reuters/RFE/RL later showed a Ukrainian Krab unit after firing in Donetsk Oblast.
Krab's conflict record is also a transfer story. Poland first supplied second-hand guns as military aid, then moved into a larger export arrangement for additional howitzers. Later Polish defense-industry reporting described the Armed Forces of Ukraine as a Krab operator and summarized both donated systems and a second Ukrainian batch ordered from PGZ Group.
