Interesting video I watched pointed out one of the major issues with the Russian military. They spend a large amount of their military budget on "Wunderwaffe" projects. Shit like hypersonic missiles, the T-14, the SU-57 and SU-75, and their Satan-2 ICBM program. Instead of pouring their R&D budget into projects they can actually afford to put into service to replace their aging aircraft and tanks, they pour it into projects designed to spook the West, but at the end of day can't actually be fielded in strategically significant numbers. Sure the U.S. also pours a lot into stupid expensive projects, but they can actually afford to field those stupid expensive vehicles fully.
