Nope.

The M1 has high fuel requirements, but someone in this thread already already pointed out that there is Soviet era equipment on the field on both sides with comparable requirements.

And the M1 has fairly low maintenance needs, and is extremely field repairable. IIRC, you can swap turrets and engine packages in the field fairly quickly.

Egypt and Saudi Arabia have fielded them for a while now, and Poland has had their training unit running for a bit, and nobody has come up with any maintenance stoppages that require US support to overcome that I've heard of.
