M4 HST

The M4 (HST) “high-speed tractor” was based on the running gear of the old M2 tank, which made it easy to develop and maintain.

It was a tracked vehicle for towing artillery pieces. Weighing 14 tons, it mounted a Waukesha 6-cylinder gasoline engine with 210 hp, which provide it a maximum speed of 33 mph (53 Km/h) and a range of 180 m (290 km).

Its cabin was designed to transport the artillery piece servers and also had a rear compartment for ammunition.

M115 Howitzer “Long Tom”

This 8-inch (155 mm) howitzer began development in 1919 under the name M1, but was soon abandoned; it was resumed in 1927, although the 1929 depression again slowed down its development. Its use in the North American army was not standardized until 1940 under the name of M115.

The two most relevant characteristics of this weapon were: on the one hand, its long barrel that earned it the nickname "Long Tom" and, on the other hand, its mounting, which is divided into two sets of balancers and includes  two-axis bogie that mounts eight wheels.
