The 44th (Philippine Scout) Infantry Regiment (44th INF (PS)) was part of USAFFE's Philippine Division during World War II. During World War I, eight Philippine Scout battalions were grouped into four provisional regiments, but were dissolved in 1920-21 when they were replaced by the creation of the 43rd 44th, 45th, and 57th Infantry Regiments (Philippine Scouts, or PS), into which many of the surviving original scout companies were subsumed. For example, the "2nd Company, Native Scouts, Macabebes" of 1901, eventually became Company D, 45th Infantry Regiment (PS), on 2 December 1920. During World War I, the Philippine Assembly had created the Philippine National Guard, which it offered to augment the AEF (American Expeditionary Force) under Pershing. The force grew to 25,000 men, but it never left the Philippines. However, a few Filipinos did see action. After the war, the National Guard was deactivated and its officers were placed on a Reserve list. At the same time of the creation of the Philippine Scout Infantry Regiments, some of the Scout Companies that had formed a Provisional Artillery unit in 1918 were converted into Batteries of the 24th Field Artillery Regt (PS). A number of other Scout Companies were mustered out or demobilized in 1920-1921 and their personnel transferred to create wholly new units; 25th Field Artillery Regiment (PS), 91st & 92nd Coast Artillery Regiment (PS) and the 26th Cavalry Regiment (PS), service and support units were organized in the Engineer, Medical, Military Police, and Quartermaster Branches. In 1921, many of the Infantry and Field Artillery Regiments were grouped together to form the U.S. Army's Philippine Division. From this point onward, the Scouts became the U.S. Army's first line of land Defense in the western Pacific.

44th Infantry (P.S.) in Hawaii

After the disbanding of the National Guard Regiments in August, 1919, the heavy duty of manning the garrison at Fort Shafter and Schofield Barracks fell to the 17th Regiment, US Cavalry Corps. They arrived in Hawaii during the spring of 1919. They were based at the Schofield Barracks until 25 September 1920. On 25 September 1920, the 35th Infantry Regiment and 44th Infantry Regiment (PS) arrived for permanent station in Hawaii. This being said, the 44th Infantry Regiment was deactivated during 1922 at Fort Shafter, Hawaii.

The Philippine Division, now redesignated the 12th Infantry Division (PS), was reactivated in 1946, along with its component units, primarily to compensate for the demobilization of American army units. The 44th Infantry Regiment (PS) was reformed for occupation duty on Okinawa and inactivated in 1949.^[3]
