Basically, it is doctrine and some technical solutions (Javelins attack tanks from the top as opposed horizontally like older anti-tank missiles) that will enable the tank to do its job.
It's curious so, that nobody asks these questions when it comes to fighter aircraft and helicopters. Because those are vulnerable to manpads as well, and the war in Ukraine shows this pretty clearly. I guess burned out tank make for better footage then some small pieces or debris in some field that only experts can tell which aircraft it used to be once.
