The Russians are claiming to have developed a tri-mode anti-tank missile. Not only is it Supersonic, but it also has optical, laser and millimeter guidance. Added sauce for this goose is the ability to launch two missiles within 4 seconds of each other and a 152mm claimed size of the warhead. In tests its supposedly been proven effective against all modern tanks, even those equipped with reactive armor.
Seeing the success of the RPG-29 in Iraq, I'd say that American Tankers and Track crews might be hoping for active protection measures sooner rather than later.
