One of the lesser-known, but equally important military vehicles used during World War II and beyond was the halftrack, a combination vehicle that had wheels in the front and tracks in the rear.

Among them all, the M3 was the most widely produced and used of the World War II halftracks, with more than 54,000 units produced as the original M3 or one of its many variations.

It was used by the Allies throughout WWII for many purposes, making it one of the more influential military vehicles in the war.

How Was The M3 Originally Developed?

The M3 halftrack was developed as a larger and more equipped version of the M2 Halftrack-car as an armored personnel carrier for use on the battlefield.

These military vehicles were equipped with an M2 browning machine gun and two M1919 machine guns on board and could transport up to a dozen troops in the rear, an increase of four from the original M2.

Improving on the development flaws of the M2 which was never approved for use in the field, the M3 eventually passed its testing by the U.S. Army in 1941 and put into active service soon thereafter.

What Were The Specs of an M3 Halftrack?

The M3 halftrack in its original design was over 20 feet in length and 7 feet in width, standing 7.5 feet high on its wheels and tracks.

The military vehicle had a gross weight of between 17,650 pounds unloaded, had a 60 gallon gas tank, and could travel 220 miles while fully loaded with twelve troops and a single driver.

The M3 was powered by a V-6 engine, built with ¼” thick armor that protected troops from small arms, and was later equipped with brackets for artillery rifles, storage beneath the seats for ammunition and rations, and racks on the outside of the vehicle for carrying land mines.

What Were Some Design Flaws?

Despite its poor turning radius, which was the main issue with it, the M3 was considered to be extremely reliable and mechanically sound, one of the more reliable of the World War II halftracks and military vehicles.

The other problem with the design was that it was open on top, providing no cover for those riding inside of it.

Referred to as “Purple Heart boxes” at one point in the war for their lack of overhead protection, it was eventually understood that due to their reliability, many troops were using the M3 in ways it was not approved for, resulting in the deaths of many of its passengers.

In Summary

When used as intended, the U.S. military had great success with the M3, which went on to be the base design for more than twenty five variants as armored personnel carriers, self-propelled guns, anti-aircraft guns, and many other military vehicles.

From the battlefields of World War II, the M3 World War II halftrack would go on to be used throughout the west, the east, and even the middle-east, with the most recent variants still in use in the 1960s in Israel.

A lesser-known military vehicle used in the two World Wars was the half-track, a combination wheeled and tracked vehicle that was the predecessor to the first tanks.

Half-tracks were mainly used as troops and equipment carriers and as such, they were not designed with combat-capable armor.

Eventually as the need for stronger and more powerful tracked military tanks and vehicles grew, the design was modified and the first military tanks were born.

Still, these half-wheeled and half-tracked vehicles were used well into World War II and beyond. 

The Beginnings of Half Track Vehicles

Half-track vehicles, which originated as agricultural vehicles, began as tractors that had two wheels in the front and a set of tracks in the back.

This unique design of the early 1900s made working in the fields easier, especially since steering with the front wheels was still possible. 

Adaption as Military Vehicles

As useful and nimble as these early half-tracks were considering the technology of the day, they were quickly adapted as a military vehicle at the start of World War I as personnel carriers.

These new tracked military vehicles used by American and German forces could be steered quickly and easily over muddy battlefields to transport as many as 12 soldiers and their weapons at one time.

They were also used to pull artillery guns, as radio and command cars, or as field ambulances that drove around to pick up injured soldiers.

They were made in numerous sizes and designs ranging from 1-ton to 18-ton vehicles, with the most nimble models reaching a top speed of approximately 31 MPH. 

Design Evolution of World War II Half-Tracks

Although they were open-topped military vehicles, World War II half-tracks were lightly armored to provide a degree of protection to their occupants.

Over time, the design of the military half-track evolved to include machine guns, howitzers, anti-aircraft guns, and even flame throwers, and many other features.

When the need for stronger armor and the ability to cross entire trenches grew during WWI, armored personnel carriers designed from the concept of the half-track were developed, followed soon after by the first actual fully-tracked tanks. 

The Importance of Half-Tracks During WWI and WWII

World War I and World War II half-tracks, though not as well-known among the military tanks and vehicles of the day, were important military vehicles that were relied on throughout both wars.

They were used extensively by military forces throughout the world until the late 1960s, though most forces discontinued their use beyond that, replacing them instead with only all-wheeled and tracked vehicles.

The production of armored personnel carriers was also continued, as these were fully enclosed, fully-tracked vehicles that became more useful. 

In Summary

Today, many military tanks and vehicles like World War II half-tracks can be found in military museums and private collections as the remaining supply of these vehicles was sold as military surplus in the 1960s and 1970s.

Some are still being used by civilians for tasks that involve travel over difficult terrain.

Half-tracks are still found in service as all-terrain fire department pumpers, while others equipped with hitches, winches, and small cranes are being used for various other jobs.
