I just don’t see how this can be a successful endeavor without NATO boots on the ground helping them out.

Sounds like you have been there done that. I have. The massive convoy of ammo, fuel, maintenance and support vehicles following a western tank company or even platoon is huge, and they usually ( depending on mission) are less than 30 miles behind.
This is going to be a HUGE embarrassment to the collective West.
Right, like the HIMARS rockets, they have been such a "HUGE embarrassment" that Poland wants to buy 500 M142 HIMARS.
