On active protection systems, I think it won't be long until we see hard counters to them appearing.
A fairly simple concept is to have a lumburg lense (with protective cap so as not to needlessly increase the RCS of the missile) attached to a mini-rocket integrated into an ATGM.
At a pre-determined range, the mini-rocket boosts off, ditching the cap to reach the tank and setting off the APS moments before the ATGM, so that the ATGM hits the tank before the APS could reset.
