2S22 Bohdana
The 2S22 Bohdana is a 155 mm NATO-standard artillery caliber, wheeled self-propelled howitzer developed in Ukraine. It is mounted on the chassis of the Ukrainian six-wheel-drive KrAZ-6322 truck. It has an armoured double cabin and storage for around 20 shells. The howitzer has a minimum range of 780 meters, and a maximum range of 40 km with HE/AP ammunition or 50 km with a rocket-assisted projectile. It has an average rate of fire of six shells per minute.

History
The howitzer underwent live-fire tests in 2018. Its first public display was in the Kyiv Independence Day Parade on 24 August 2018. Test firings were conducted at the Shyrokyi Lan training ground in May 2021. Further test firings were carried out at a range in Odesa Oblast in December 2021 and January 2022, where 450 shots were fired at a range of 42 km, greater than the manufacturer's specification of 40 km.

In January 2023, the 2S22 entered full production according to defense minister Oleksii Reznikov. The first units will be delivered in the next few months.

Russo-Ukrainian War
On 25 February 2022, at the start of the Russian invasion of Ukraine, the Bohdana's manufacturers were ordered to destroy the sole prototype, to prevent the Russians from capturing it. However, it was able to be moved away from the Russians and handed to the Ukrainian Armed Forces. On 7 May 2022 Forbes reported that the prototype had been deployed at the front and was firing at Russian targets. 

In June 2022 Ukrainian forces on the mainland of Ukraine reportedly used the 2S22 Bohdana to shell Russian forces on Snake Island, which is 35 km from the mainland. This along with strikes from other artillery systems as well as drones led to the withdrawal of Russian forces from the island on 30 June.

Ukrainian defense minister Oleksii Reznikov stated at the beginning of 2023 that serial mass production of an improved Bohdana has started. The improved version includes the replacement of the KrAZ-6322 chassis with a KrAZ or MAN 6x6 chassis, or a Tatra 817 8x8 chassis. On July 2023, a video showing the 57th Motorized Brigade operating at least two pre-production Bohdanas mounted on the MAZ-6317 chassis (with the original Russian engines replaced with Chinese engines) was published. The 2S22 Bohdana was officially adopted by the Ukrainian Armed Forces on 21 July of 2023. Two days later, an improved Bohdana mounted on the Tatra 815-7 8x8 chassis was reported as being in service with the 1st Special Purpose Brigade.
