The M75 is an early Cold War era armored personnel carrier of US origin. It was developed in the late 1940's by the International Harverster Corporation to replace the halftracks used in World War 2. The M75 was the first design in a series of US armored personnel carriers that resembles a metal box on tracks. Although the M75 functioned quite well and had a good level of protection its huge cost, high weight and limited mobility resulted in production to be halted early. As a result the M59 and later the successful M113 were developed, both vehicles share the general layout of the M75.


The M75 looks like a box on a tracked chassis, which was derived from the chassis used on the M41 light tank. The driver is seated at the front left with the engine to his right. The crew compartment is located at the rear and is accessed by two doors in the rear.


The M75 is armed with a single 12.7mm M2HB heavy machine gun on a ring mount for which 1.800 rounds are carried.


The thick steel hull provides the crew from small arms fire and shell splinters. The level of protection is thicker than needed for stopping 7.62mm rounds, but is not fully adequate for stopping 12.7mm rounds. An NBC system and smoke grenade dischargers are both lacking.


The tracked chassis allows the M75 to cross allmost any terrain. Due to the heavy weight the M75 is not amphibious and has a limited mobility. The average speed is low, although a top speed of 71 km/h can be achieved. The operational range is very limited due to a high fuel consumption. Propulsion is provided by a Continental 295 hp gasoline engine.


The main user of the M75 was the US Army and the M75 was actively used in small numbers in the Korean war. After the war it was replaced by the lighter M59 and large numbers ended up in Belgium and a smaller batch in Ethiopia. Since the early 1980's the M75 is no longer in service.



The M75 was produced only in a single variant, the armored personnel carrier. During production numerous small changes were made to reduce the production cost. These changes include the change from two rubber fuel tanks to a single metal one and the removal of some shock absorbers.
