The M1301 Infantry Squad Vehicle (ISV) is a new, lightweight, all-terrain troop carrier designed to modernize U.S. Army Infantry Brigade Combat Teams (BCTs). It is based on the Chevrolet pickup truck Colorado ZR2 architecture, deriving 90% of its parts from commercial-off-the-shelf components. The U.S. Army will field ISVs to 11 Infantry BCTs for a total of 649 ISVs by Fiscal Year 2025.
