Military Districts of the Philippines

As part of the military reforms introduced in 1942 the Republic of the Philippines was divided into ten military districts, each responsible for the administrative control of military units, formations, military schools, and various local military establishments, both of the Regular Army and the reserves. This territorial system was adopted to provide a more efficient management of army units, their training and other operations activities related to combat readiness.

The Military Districts were established as follows:

Military District One: Baguio, Luzon
Military District Two: Tarlac, Luzon
Military District Three: San Fernando, Luzon
Military District Four: Lipa, Luzon
Military District Five: Daraga, Luzon
Military District Six: Iloilo City, Iloilo
Military District Seven: Bacolod, Negros
Military District Eight: Cebu City, Cebu
Military District Nine: Tacloban, Leyte
Military District Ten: Davao, Mindanao

The establishment of five districts on the island of Luzon reflected the new postwar strategic orientation of the Philippine Army, which saw the principal threat being the possibility of renewed Chinese aggression and direct attacks on Luzon.

Infantry Division (Motor Transport) – 1942 Establishment

The previous divisional establishment of the Philippine Army was found to be oversize and cumbersome, particularly when the large divisions were mobilized in the fall of 1941. On the whole they lacked modern transportation. In 1942 a new establishment was promulgated, which reduced the field strength of the division from some 18,000 officers and men to a much more manageable 13,000; this also permitted the formation of additional divisions without too great an increase in the size of the Army.

The new divisions comprised:

Divisional headquarters element
Three infantry regiments, each of three battalions
One cavalry regiment, for reconnaissance
One artillery regiment of four battalions – three with 75mm field guns and one with 105mm field howitzers
One antiaircraft battalion
One engineer battalion
Divisional service and medical troops

Tabular information:

Officers: 476
Non-commissioned Officers: 1,729
Enlisted Personnel: 10,646

M1911 Pistol: 2,386
M1933 Rifle: 10,384
M1928 Sub-machinegun: 480
M1933 Light Machinegun: 417
M1938 Heavy Machinegun: 130
M1937 Mortar: 54
M1931 Mortar: 82
M1936 Antitank Gun: 29
M1932 Field Gun: 36
M1933 Howitzer: 12
M1934 Light Antiaircraft Gun: 27

The establishment called for 1,569 motor vehicles per division – including 462 field cars, 825 light trucks, 234 medium trucks and 48 gun tractors.

Infantry Division (Light, Mountain) – 1942 Establishment

The standard infantry division of the Philippine Army, even in its revised 1942 Establishment, was considered to be too road-bound for employment in many of the mountainous areas of the country, such as Mindanao. Therefore an alternate, light division was envisioned, relying principally upon animal transport and with a slightly smaller complement of heavy weapons. The standard field artillery regiment was replaced by a mountain artillery regiment of three, rather than four, battalions.

The new light (mountain) divisions comprised:

Divisional headquarters element
Three infantry regiments, each of three battalions
One cavalry regiment, for reconnaissance
One artillery regiment of three battalions with 75mm mountain guns
One antiaircraft battalion
One engineer battalion
Divisional service and medical troops

The establishment provided for 467 motor vehicles – chiefly field cars and light trucks; and 2,567 animals, including 1,336 mules.

Mechanized Brigade – 1942 Establishment

Experience with the Armored Brigade formed in 1940 had shown that organization to be unbalanced and cumbersome. As part of the Army’s reorganization the single armored brigade was broken up and combined with other mechanized troops to form several independent all-arms brigades.

It comprised:

One light tank battalion
One motorized infantry battalion
One reconnaissance battalion
One motorized artillery battalion
One antiaircraft company
Service elements

[Historical] Philippine Infantry Division - 1940

1st Infantry Division circa 1940: (Four in service)

The 1st Infantry Division was based in the island of Luzon and was ordered to be fully mobilized in September 1940 due the rising tensions with China at the time. There were three additional infantry divisions in the Filipino Army at the time but actual organizations and equipment in the divisions vary from unit to unit, the main changes in the equipment assigned to the artillery regiment and some of the divisions have additional supporting units attached. While officially the units were reported to the World as 12,000 men strong fully mobilized the Filipino divisions were considerable larger, closer to 20000 than to 10000 men. The 1st Division is composed of three infantry regiments composed of three battalions each; an artillery regiment, a cavalry or motorized battalion, an engineer company, an AA company, an AT company and other supporting elements.

• 9 × 75mm Skoda-Davao towed cannons (2)

(2) The artillery regiments of the Division were organized differently. The 2nd Division had 24 75mm and 24 105mm artillery pieces; the 3rd had 36 75mm artillery pieces, and the 4th had 18 75mm and 24 105mm artillery pieces.
(3) Large number of antitank guns is because they are also utilized as infantry support weapons and issued with anti-personnel rounds in addition to AT rounds.
(4) Skoda-Davao copy of Type 85 Japanese gun.
(5) Only Division with Tank Company attached. Utilized a 57mm high-velocity gun developed by Skoda-Davao.
