[2] Fielding began in 2021, along with initial operational test and evaluation (IOTE);[4] 649 ISVs are to be allocated to 11 infantry brigade combat teams (IBCTs) by 2025.

The Army never formalized a competitive bid process, but in the interim, opted to purchase a limited number of GMVs through SOCOM's Ground Mobility Vehicle 1.1 program.

[6] The operational requirements of the ISV were nine passengers, a payload of 3,200 pounds (1,500 kg), transportable by external sling load by a Sikorksy UH-60 Black Hawk helicopter, internal load/external lift by Boeing CH-47 Chinook helicopter, low-velocity air drop by Lockheed C-130 Hercules or Boeing C-17 Globemaster III transport aircraft and exceptional mobility over all terrains allowing Infantry Brigade Combat Teams to move with their equipment over difficult terrain.

It is capable of seating 9 personnel (the size of a standard US Army rifle or weapons squad) in a 2/3/2/2 configuration within a simple roll-over protection structure.

The ISV is powered by a Duramax 2.8L turbocharged direct-injection diesel I4 engine connected to a Hydro-Matic 6-speed automatic transmission and 2-speed transfer case.

[11] The M1301 ISV was first used by 2nd Brigade, 101st Airborne Division in a Defense Support of Civil Authorities mission to provide aid to Hurricane Helene victims in eastern Tennessee and western North Carolina in October 2024.

ISVs were transported via internal load in CH-47 Chinook helicopters and via a 350 mile (563 km) convoy from Fort Campbell, KY to Asheville, NC.
