Classic Morale Operations (MO) T-shirt
How to Find Your Perfect Fit
Don't guess your size! The best and most accurate course of action is to measure an existing, good-fitting shirt from your closet and compare those measurements to our charts below.
- Width at Chest: Lay the shirt flat and measure 1 inch below the armhole, from side seam to side seam.
- Back Length: Measure from the center back neckline down to the bottom hem.
- Width at Shoulder: Measure straight across the back from shoulder seam to shoulder seam.
- Sleeve Length: Measure from the shoulder seam down to the end of the sleeve.
Note: Measurements are in inches. Allow for a standard manufacturing tolerance of +/- 0.5 to 1 inch.

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.
