CHAPTER VII.
MOTORIZED ARTILLERY.

Complete motorization of field artillery and its ammunition supply is almost certain to be one of the far-reaching and highly important results of our country's experiences in its participation in the war.

Practically all field artillery was of the horse-drawn type previous to our entry into the war, but with the evolution and perfection of the heavier siege artillery, 5-ton, 10-ton, and even heavier, traction engines were brought into play as means of motive power for the big guns and howitzers, with such success that the horse in the field artillery operations was being supplanted to a large degree by mechanical power.

Strictly speaking, the foundation for this departure had been laid before 1917, in the Mexican campaign of 1916 and in experiments that had been conducted at the Rock Island Arsenal. Insufficiency of funds, however, had prevented the experiments from being either thorough or extensive.

A consideration of the difficulties that vehicles of all sorts had to contend with in the battle areas of Europe made it evident at the outset that two general types of motor carriers would be required by the Army so far as ordnance was concerned—one type for far-advanced work, for hauling artillery over the worst possible kind of shell-torn and water-soaked earth, and the other for bringing up ammunition, supplies, equipment for repairs and the like in less advanced zones and areas, but over roads and country that had been cut and hacked and made almost impassible by the activities of the contending forces.

TRUCKS.

The standard four-wheel-drive commercial trucks, modified to meet the special needs of the service, were adopted immediately after war began, while experimental work was put under way to develop a standard type that would set this country far in advance of all others in this line of activity.
