Why It Matters
The Army raised its Infantry Squad Vehicle (ISV) procurement objective to 11,582 vehicles in February, more than four times the 2,593-vehicle objective set at full-rate production approval in March 2023, according to a new Congressional Research Service (CRS) report.
The Army describes the increase as "exponential growth" driven by "soldier feedback and TIC experimentation" and "operational demand."
As of November 2025, the Army had fielded at least 1,105 ISVs across 10 units, approximately 43% of the full-rate production objective of 2,593 vehicles set in March 2023. The gap between vehicles fielded and the new 11,582-vehicle target puts the scale of the Army's ambition in concrete terms for appropriators and oversight staff.
The Big Picture
The ISV is a lightweight, unarmored transport built by GM Defense on a Chevrolet Colorado ZR2 platform, with about 90% of its parts drawn from commercial off-the-shelf (COTS) components. The Army adopted the COTS approach to minimize costs and field the vehicle quickly, intending it to move nine soldiers and their equipment across terrain where heavier vehicles may be less practical.
In 2021, the Department of Defense Director of Operational Testing and Evaluation found the ISV effective as a troop carrier in permissive environments but noted limitations in combat roles related to reliability and training. A 2023 evaluation reported significant reliability improvements after corrective actions, but stated its survivability assessment was "unchanged from the December 2021 Initial Operational Test and Evaluation (IOT&E) Report."
The Army's fiscal 2026 budget request included $308.620 million for procurement of 1,275 ISVs. On March 30, the Army released a Commercial Solutions Opening for a heavier variant, the ISV-Heavy, under which it could award up to three contracts for 606 vehicles.
The Bottom Line
The report frames several questions for congressional consideration: how an ISV-Heavy procurement would affect the original ISV program; how single-vendor COTS reliance affects lifecycle costs and supply-chain resilience; whether industry can sustain a fleet of 11,582 or more vehicles in wartime; and how ISV requirements affect the rest of the Army's Light Tactical Vehicle fleet.
