That company was among those chosen to represent the Marine Corps at the Philadelphia Exposition of 1926, until it was called out to guard the mails during an outbreak of robberies.

He fought in several engagements against rebel bandits in that country and was awarded the Navy and Marine Corps Medal for an action near Buena Vista on 19 January 1928.

Returning from Guam in July 1935, Brown served for two months as executive officer of the rifle range detachment at Quantico before entering the Base Defense Weapons Course in the Marine Corps Schools there.

There, he was Assistant Acting Quartermaster and member of the Naval Retiring Board until June 1939, when he took command of the Marine detachment aboard the USS Pennsylvania (BB-38).

Returning to the United States in January 1943, he was assigned to San Diego until he entered an advanced artillery school at Fort Sill, Oklahoma.

During this period, four army infantry regiments and two Marine Corps divisions were trained in amphibious warfare at the base, and Brown became one of the pioneers in the coordination of naval gunfire, artillery, and air support.

Returning from China in October 1946, General Brown was assigned to the Air University, Maxwell Field, Alabama, as an instructor in the Naval Division.

When one of his assault battalions was subjected to an accurate enemy mortar and artillery barrage which inflicted heavy casualties, including four company commanders and ten other officers, Colonel Brown proceeded to the area in the face of the murderous fire and skillfully reorganized the battalion, enabling it to continue the attack.

By his inspiring leadership, aggressive fighting spirit and courageous initiative, Colonel Brown upheld the highest traditions of the United States Naval Service.
