The TRF1 appears in the 2014 Russia-Ukraine War record through French transfer documentation, Ukrainian service-adoption reporting, and battlefield loss evidence. France's Ministry for the Armed Forces listed six TRF1 howitzers among equipment delivered to Ukraine from February 24, 2022, through December 31, 2023, and separately listed 30,000 rounds of 155 mm ammunition for CAESAR and TRF1 guns.
Le Monde reported in October 2022 that France had sent fifteen 155 mm TRF1 towed howitzers to Ukraine. Ukrainian reporting later said the Armed Forces of Ukraine adopted the TRF1 155 mm howitzer into service by a Ministry of Defence order dated August 28, 2023. Oryx's visually documented Ukrainian loss list records destroyed and damaged 155 mm TRF1 howitzers under Ukrainian towed artillery, confirming battlefield presence beyond transfer announcements.

Timeline
Public reporting first tied the TRF1 package to Ukraine in autumn 2022, during France's broader shift from early protective and anti-tank aid toward heavier artillery support. Le Monde reported the TRF1 transfer on October 11, 2022, and Babel reported on December 12, 2022, that French Defence Minister Sebastien Lecornu had said six TRF1 155 mm towed howitzers had been handed over to Ukraine.
Ukraine's formal adoption reporting followed in August 2023, when Ukrainska Pravda cited the Ministry of Defence of Ukraine for an order adopting several foreign artillery systems and mortars, including the TRF1 155 mm howitzer. The French official delivered-equipment list published in 2024 then gave the quantified delivery baseline through the end of 2023.

Narrative
In Ukrainian service, the TRF1 filled the same broad role as other Western-supplied 155 mm artillery: indirect fire support with NATO-standard ammunition. The sources directly support transfer, adoption into Ukrainian service, ammunition supply, and battlefield presence; they do not establish a complete unit-by-unit deployment history or a comprehensive count of guns in action.
The available record separates three stages. The French and Le Monde sources document transfer to Ukraine. The Ukrainian service-adoption report documents incorporation into the Armed Forces' foreign-artillery inventory. Oryx's visually documented losses show TRF1 guns on the Ukrainian side of the battlefield, including destroyed and damaged examples, but do not by itself identify every firing unit or engagement.
