Direct proof of use
The Strv 122 is documented in the 2014 Russia-Ukraine War through Swedish government transfer records and Swedish Armed Forces battlefield reporting. Sweden's February 2023 support package for Ukraine included Leopard 2 tanks, and the Government Offices of Sweden identified the Stridsvagn 122 as Sweden's version of the German Leopard 2.
On 21 September 2023, the Swedish Armed Forces reported that ten Stridsvagn 122 tanks were on the battlefield in Ukraine, manned by Ukrainian crews trained in Sweden. The same article said Sweden had donated roughly a tenth of its 120-tank Strv 122 fleet and described the Ukrainian crews' summer training in Sweden.

Narrative
Ukraine received the Strv 122 as a small, high-value armored package rather than as a mass fleet. The February 2023 Swedish announcement framed the tanks alongside Archer artillery and HAWK air-defense components as heavy advanced weapons for Ukraine, while the September Swedish Armed Forces article described Ukrainian soldiers trained by Swedish Army personnel before the tanks entered Ukrainian service.
In Ukrainian service, the Strv 122's documented function is armored battlefield employment by Ukrainian crews. Swedish Armed Forces reporting described the tanks as intended for use with Swedish combat vehicles, and its facts section identified the armament as a 120 mm smoothbore gun, two 7.62 mm machine guns, smoke grenade launchers, armor-piercing and high-explosive ammunition, and target engagement out to about 4 km.
Publicly available sources support transfer, training, deployment, and battlefield presence more clearly than they support individual named engagements. Army Recognition's October 2024 account reported Ukrainian Strv 122s in combat, losses, and protective camouflage in eastern Ukraine, but the page's core claims rest on Swedish official sources rather than social-media loss counts or unverified footage.
