> The lower down the echelon, the nearer the armies of the world came to standardizing psychological warfare organization. They did this for the same reason that they all organize into regiments instead of centuries, cohorts, or tribes. Modern war is a self-standardizing process if the enemy experience is to be copied, enemy techniques improved, allied assistance accepted, and military practice kept up to world standards. Psychological warfare units needed printing and radio sections; to service these sections they all needed intelligence and analysis offices; to distribute their materials they all needed agents and liaison. Black propaganda organization varied more than did white, but it was amazing to Americans, uncovering Japanese subversive-operations units, to see how much the Japanese organization resembled their own.
