My choice / thoughts.....
CROW system versus crew commanders noggin exposed with the equal of a GAU19 in 12.7 or M134DT Dillon minigun.... maybe a stubby barrel main gun like the old engineering M48 patton or M558 with the 152mm Demolition main gun used to kill bunkers and buildings...... add RPG screens and reactive armor for dual shape charge munitions.....
And of course their variant of the M9 dozer blade ...
Ivan used water-filled thin-wall aluminum tubing as add-on armor on BMP and BMD personnel carriers in Afghanistan and Chechnya. And, of course, if not needed as backup armor, it's a nice additional supply of water as well.
