To be honest, those tanks will probably have far more to fear about Russian artillery.
Cheap, small commercial drone spotted artillery has been almost revolutionary in this war due to how effective is has been in erasing armour on both sides that actual tank-on-tank engagements have been exceptionally rare.
That won’t change for Leo’s or Abrams. There will be plenty of propaganda shots of them when they first arrive, but they are almost certainly not going to chance things much on the battlefield.
They either operate in small numbers to minimise chances of attracting Russian artillery and air power, and thus have minimal impact; or if they try a mass armoured charge with them, the Russians will quickly detect and prioritise that push and will respond by spamming the shit out of them with artillery and grads. Any tanks that do survive the artillery will soon find themselves on the receiving end of Russian CAS from Su25s and attack helicopters. By the time T90s actually show up there will probably be nothing by wreckage left.
The problem is that there is seemingly no coordination between Russian units at scale.
You aren't seeing something like the coordination between army and aviation units as you describe.
If the logistics were up to supporting forces at forward operations areas, they likely would not need to fall back as they have the past few months.
Mix in AT Infantry and Sappers doing AT Mining to your scenario and there really should not be an issue to deal with tanks at all, but I’m not sure it is within the capabilities to pull it off.
