Well we know for sure that the RuAF VDV took mass casualties at Hostomel and in Irpin.
A number of front-line Ru units have been declared combat ineffective. Especially those who were based in the Kharkiv oblast that was liberated last November. The 1st and 4th Guards tank armies were malleted as well as 2nd Guards MRD and the 11th army corps got mauled.
During the siege of Bakhmut it was mainly Wagner , criminal z-storm units and DNR units that were used. Now however Regular RuAF are on the front-line along with VDV units. If reports are to be believed the VDV units have sustained mass casualties south of Bakhmut. Kadyrov’s Chechens are not proper soldiers and invariably run away from battle at the first opportunity.
As for Adviikda we have seen the RuAF 25CAA being used as meat assault units and they have / are being chopped up.
So in summary I’d say that
@ramacca needs to do a little more research.
