The British Defense Ministry shared the report on Twitter.
According to British intelligence, Russia is preparing to try to deploy a large number of reserve units in the Donbas.
The Russian authorities don't report the total number of military losses in Ukraine, but the DPR has released its data. Thus, since the beginning of 2022, 2,128 soldiers have been killed and 8,897 wounded.
"The DPR casualty rate is equivalent to around 55 per cent of its original force, which highlights the extraordinary attrition Russian and pro-Russian forces are suffering in the Donbas. It is highly likely that DPR forces are equipped with outdated weapons and equipment. On both sides, the ability to generate and deploy reserve units to the front is likely becoming increasingly critical to the outcome of the war," the UK intelligence added.
