The Infantry Squad Vehicle’s physical specifications reflect a deliberate design philosophy: prioritize transportability and mobility at the cost of protection and payload. Understanding the vehicle’s dimensions, capacity, and deployment options explains why the Army chose this platform for its most mobile formations.
Physical Specifications
The ISV measures approximately 17 feet in length, 6.8 feet in width, and 6 feet in height — roughly comparable in footprint to the HMMWV, and notably smaller than the JLTV. Its payload capacity is near 3,200 pounds, which is less than either the HMMWV or JLTV.
The vehicle includes a Roll Over Protection System (ROPS) and was designed from the outset with air deployability as a core requirement rather than an afterthought.
Air Transport Options
The ISV can reach the battlefield by multiple air platforms:
- Fixed-wing air landing or low-velocity airdrop: C-17 Globemaster III, C-130 Hercules, A-400M Atlas
- Internal helicopter load: CH/MH-47 Chinook, CH-53E/K Super Stallion and King Stallion
- Sling load: UH-60 Black Hawk
This flexibility allows the ISV to be moved through the full range of Army and joint air assets currently in service, giving commanders multiple insertion options depending on threat environment and available aircraft.
Variants and Third-Party Kits
GM Defense offers a flatbed ISV variant configurable for a two- or five-person crew that can be adapted to a range of functions beyond standard troop transport. Third-party vendors — not GM Defense — have developed additional “kits” to expand the ISV’s mission set, including a casualty evacuation kit for externally transporting wounded personnel and a command-and-control variant.
These options expand the ISV’s utility beyond its core role as a nine-soldier transport without requiring a fundamentally different platform, which is consistent with the Army’s cost-control approach to the program.
The Trade-Off the Army Accepted
The ISV is intentionally unarmored. It offers no ballistic protection of the type found in the JLTV or HMMWV. The Department of Defense’s Director of Operational Testing and Evaluation noted in 2021 that the ISV was effective as a troop carrier in permissive environments but had limitations in combat roles — an assessment that reflects the vehicle’s intended use case rather than a design failure. The ISV is not meant to replace armored platforms; it is meant to fill the mobility gap those platforms leave open.
