Concealment

In U.S. military doctrine, concealment protects against observation or detection by intelligence, surveillance and reconnaissance, or by simple tactical observation. The classic visual form of concealment is camouflage, but so is hiding a facility underground or inside a building. Electronic warfare includes a wide range of concealment methods, including jamming sensors so they cannot detect the object of interest, or using deceptive decoys to draw attention from the real object or electronic signal.

It is a subset of deception, and of the even broader Russian/Soviet concept of maskirovka.
