Another round of recommendations:
A war metal super-group featuring members of Blasphemy, Revenge, and Conqueror.
This is a noisegrind project (not war metal) that has been influential to a number of the bands listed above. The vocalist has collaborated with RotUGF, Konflict, and others.
A war metal band from Texas, USA that has a particularly chaotic sound.
A Japanese war metal band with added experimental and atmospheric aspects.
An American war metal band with a harsh and bestial sound.
A Canadian war metal band that retains the pure essence of the genre, eschewing the noise that many others now incorporate.
A Turkish war metal band that, much like Necroholocaust, retains a pure black/death metal sound.
