On May 17, the Ukrainian Main Intelligence Directorate of the Ministry of Defense revealed that they had obtained official Russian documents proving that Russia’s 1st Tank Army had suffered huge losses in terms of tanks and troops in its invasion of Ukraine. It is important to note that SOFREP cannot independently verify the legitimacy of these Russian documents. However, there is circumstantial evidence to believe the massive losses of the Russian 1st Tank Army as reported by independent, open-source data collectors who are monitoring military equipment losses in Ukraine.

According to the documents obtained by Ukrainian intelligence, the papers reveal that the 1st Tank Army had incurred casualties of some 409 troops, killing 61 and wounding 209, with 44 missing as of March 15. Ninety-six troops were also taken as POWs.

“As of March 15, 2022, the total losses of 1 Russian tank army were 409 people. Ukrainian soldiers eliminated 61 and wounded 209 invaders. Only in the first two weeks of the war, 44 Russian tankers disappeared, and 96 occupants from this army decided to save their lives and surrendered,” the Ukrainian Main Intelligence Directorate said in a Facebook post.

“At the same time, the defenders of Ukraine were destroyed and captured 308 units of combat equipment from the said army of occupiers,” they added. The document also indicates that the 2nd Motorized Rifle Division’s 1st Tank Regiment lost 45 T-72B3M. This would mean that the 1st Tank Regiment would have lost over half of its tanks as the regiment supposedly had 93 units.

The document also reveals the grim number of losses of the Russian 4th Tank Division, with the 12th Tank Regiment losing 18 T-80Us. The 13th Tank Regiment also reportedly lost 47 T-80UE tanks, and the 423rd Motorized Rifle Regiment lost 6 T-80BVs. Furthermore, the 27th Motorized Rifle Brigade had lost 9 T-90A tanks. There is a bit of a mismatch beween the number of casualties to crews versus tanks.  This could be due to a number of crews abandoning their vehicles allowing them to be captured or represent tanks destroyed at night when the crews would not be inside them.
