The Carrier, Personnel Half-track M5, also known as the M5 Half-track, was an American armored personnel carrier from World War II. It was produced in the United States by International Harvester as a supplement to production of the M3 Half-track. It was supplied to Allied nations (the British Commonwealth, France, and the Soviet Union) under the Lend-Lease. After the war it was leased to many countries in the NATO.
The M9 Half-track was the same vehicle but with a different internal layout to fulfill the same purpose as the M2 Half Track Car.
