The most elegant solutions are always the simplest. 

As an 18xx series, ive done plenty of tandem training with my fellow Abrams operators, and what holds them up is typically the same thing that holds us up:

Destroyed tracks via steel cable or concertina wire

It doesnt take much. A steel cable or wire wrapped up in the tracks of a tank (or any other tracked vehicle) will stop it immediately. Simply place the wire or cable at odd angles in areas the tanks are operating, and they will get wrapped in either the road wheels or idler wheels. 

This is a big deal because not only is the vehicle basically "dead" in the sense that it cannot move (you cant really operate or maneuver warfare if the vehicle can't drive), but in order to fix the vehicle you have to either A. tow it, which is a hassle in and of itself, or B. "throw track", where you pull the tracked component, by hand, off of the vehicle and replace it upon pulling out the wire or cable, which can take, at a minimum, hours.
