Tanks are always on the verge of being declared obsolete. Yet heavy armor continues to prove its value. In the long battle between guns/missiles and armor which has been supplemented by active defenses, passive defenses have made some new progress:

There appears to be another breakthrough in armor protection. The new one is CMF (Composite metal foam) that is produced by bubbling gas through molten metal to a lightweight metal matrix.

Strategypage reports that smaller vehicles and infantry body armor will likely be the first beneficiary of this technology.

I assume heavy armor and ships will benefit eventually.
