The modern U.S. Army Psychological Operations (PSYOP) branch traces a significant portion of its lineage, tactics, and operational philosophy directly back to the Morale Operations (MO) Branch of the Office of Strategic Services (OSS) during World War II.
While the conventional U.S. Army had its own psychological warfare units during the war that focused on open, “white” propaganda, the OSS MO Branch pioneered the covert, deceptive, and highly targeted “black” propaganda that heavily influences modern special operations.
Established on March 3, 1943, the Morale Operations Branch was the brainchild of OSS Director General William “Wild Bill” Donovan. Donovan had observed the formidable impact of Nazi propaganda and the success of the British Political Warfare Executive (PWE). Recognizing that the United States lacked a comparable capability, he created the MO Branch to wage psychological warfare.
