As a side note...NATO (reserve) tanks get about 10 hours of maintenance every month for each and every vehicle. There's 100's of different mechanical mechanisms (weapons loading actions, main gun elevation, ammo movement trollies, turret gears, engines, transmissions, suspension on each wheel, and the pivots on each track link) that need to be properly lubed and kept free of rust and moisture. Then there's the hydraulic systems that can sit without seals corroding and the fluids collecting moisture. Then you get to the electronics, the batteries, the generators etc.. The Russians haven't needed more than a few planes or tanks at any one time since Afghanistan in the 80s. Nowhere near the NATO schedule. Same goes for Missiles, ICBM's, AA, helios, Howizers, Training, etc. Americans aren't going without free health care for nothing!
