Russian forces have almost certainly suffered thousands of casualties during its attack on Ukraine, says the statement of the Intelligence Service of the British Ministry of Defense, APA reports.
"Russia is likely now looking to mobilise its reservist and conscript manpower, as well as private military companies and foreign mercenaries, to replace these considerable losses. It is unclear how these groups will integrate into the Russian ground forces in Ukraine and the impact this will have on combat effectiveness," the statement reads.
