Since the end of the Cold War in 1992, the only major new threats to tanks and other armored vehicles have been remotely detonated improvised explosive devices (IEDs) used in asymmetric warfare and weapon systems like the RPG-29 and FGM-148 Javelin, which can defeat reactive armor or shell armor. Both those weapon systems use a tandem warhead where the first stage of the tandem warhead activates the reactive armor, and the second stage of the tandem warhead defeats the shell armor by means of a High Explosive Anti Tank (HEAT) shaped charge.
