Metis-M & Kornet AT Missiles vs. Merkava Tanks

[PlasmaKrab]

If you dig a bit further into it, I think you will find that NERA is another (commercial) name for a type of composite armor also called bulging armor, which uses a layer of soft non-metallic material (e.g. rubber) to the same effect as the original explosive layer (i.e. expanding after the impact and displacing the outer metallic plate).
Since it is advertised diversely as new-generation ERA and advanced passive armor, that can cause a confusion in some sources.
