Mao, Che, and Nkrumah all wrote text about waging guerilla warfare. Likewise, there's various counterinsurgency text and manuals written by agents of reactions on how to crush revolutionaries. Western Marxist theory won't touch warfare because Western Marxism is completely academic and out of touch with class struggle, let along class warfare. A bunch of tenured professors couldn't be bothered to support the TA strike, so what makes you think they would care about warfare waged by a revolutionary organization?
