Upon his graduation in June 1934, he was ordered to the Marine Corps Schools, Quantico and served as an instructor there until early 1937, when he was transferred to 4th Marine Regiment and sailed for China. He was stationed at Shanghai International Settlement under the command of Colonel Joseph C. Fegan and participated in the guard duties during a period of tensions between China and Japan. Hogaboom was ordered back to the United States in 1939 and ordered back to the staff of Marine Corps Schools, Quantico as an instructor. During his second tour at Quantico, he was deeply involved in the development of the amphibious warfare doctrine, its tactics and techniques.
