till, as the saying goes: quantity has a quality all of its own
Ish, but I'd contend quantity doesn't necessarily confer capability. Just look what Russia has available in key capabilities you'd expect for a modern air force e.g. tanking, AEW. Not much of note there. As for nice-to-haves such as CSAR, recall their half-arsed attempt to rescue the crew of the Su24 which was dealt with with ease by those Turkish F16s a few years back, the helicopter in question being taken out by an anti-tank missile as soon as it landed.
I think Ukraine may be a way tougher nut for Russia to crack now, esp with their growing capability with Turkish-built drones, which proved themselves so effective in Nagorno-Karabakh (armour, trucks, artillery, sheesh the operators even got so bored they started picking off individual troops in foxholes). Just have a fleet of these patrolling up and down the border, ready to plink anything which crosses the line.
