M1 Tank Platoon*
*
The USA Congressional record has an approval for the sale of a number of stockpiled M1A1 Abrams.  It is unclear if the sale ever went through because the political climate shifted drastically after the sale was announced.*

In any case, the Abrams would only be able to operate in certain highly built-up areas of the country due to its heavy weight.  It is provided in a platoon-sized formation for hypothetical urban conflict.*
