Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether his Department has made an estimate of the number of mercenaries serving in Russian private military companies who have (a) been killed in action, (b) been wounded and (c) deserted their post since February 2022.

We estimate that approximately 450,000 Russian military personnel have been killed or wounded, and tens of thousands more have already deserted since the start of the conflict. The number of personnel killed serving in Russian private military companies (PMCs) is not clear.

We also estimate that over 10,000 Russian armoured vehicles, including nearly 3,000 main battle tanks, 109 fixed wing aircraft, 136 helicopters, 346 unmanned aerial vehicles, 23 naval vessels of all classes, and over 1,500 artillery systems of all types have been destroyed, abandoned, or captured by Ukraine since the start of the conflict.
