Russia's military has been suffering from accidents, decaying infrastructure and lack of abilities to upgrade in many areas. Interestingly after 1991 they stopped making spare parts for their choppers, believing that can always buy it abroad, which turned into a problem after the sanctions hit.
Of course Russia retains a formidable capabilities, but they have a real problem to deal with.
Basically the only reason why we still consider Russia a Great Power is because of its nuclear weapons.
This statement doesn't make much sense unless you assume there are only two Great Powers.
