The ISV, developed by GM Defense, represents a key advancement in modernizing the U.S. Army's Infantry Brigade Combat Teams (IBCTs). Based on the 2020 Chevrolet Colorado ZR2 midsize truck, the ISV is designed to quickly and efficiently move squads around the battlefield. Its lightweight, all-terrain design, combined with 90% commercial off-the-shelf (COTS) parts, makes it a versatile and cost-effective solution for the Army.

Weighing only 5,000 pounds (2,270 kg), the ISV is engineered for rapid ground mobility. It can be sling-loaded by a UH-60 Blackhawk helicopter or transported internally by a CH-47 Chinook, ensuring quick and efficient deployment in various operational scenarios. The vehicle is designed to carry up to nine soldiers and their gear, making it an ideal platform for maneuvering squads in both urban and rugged environments.

The ISV is powered by a 2.8-liter Duramax diesel engine, delivering 186 horsepower and 369 lb-ft (500 Nm) of torque. This engine, combined with advanced automotive technologies such as the GM Hydro-Matic 6L50 six-speed transmission and GM AutoTrac two-speed transfer case, ensures that the vehicle can handle extreme off-road conditions while maintaining highway speeds.

The ISV offers several crucial advantages on the battlefield. It enhances the flexibility of entry operations, allowing soldiers to quickly penetrate hostile environments. Additionally, it counters anti-access strategies employed by adversaries, ensuring that U.S. forces maintain mobility even in contested areas. The vehicle's modular design also supports a variety of mission-specific kits, including options for casualty evacuation, nighttime operations with infrared lighting, and heavy weapon mounts.

The U.S. Army has ambitious plans for the ISV. Following a contract awarded in June 2020, the Army plans to deploy 649 vehicles across 11 IBCTs by 2025. By April 2023, 300 vehicles had already been delivered, with five brigades equipped and ready for deployment. The ISV, officially designated as M1301, is also available in standard and all-electric variants, and future updates include an armed version equipped with a .50 caliber machine gun.

The development of the ISV is a testament to the U.S. Army's commitment to maintaining a technological edge on the battlefield. By leveraging proven commercial technologies and adapting them to meet military requirements, GM Defense has provided a reliable, effective, and affordable solution to enhance the operational capabilities of U.S. forces. As the Army continues to field these vehicles, the ISV will undoubtedly play a crucial role in the mobility, survivability, and lethality of U.S. forces in future conflicts.
