Showcased to invited guests at the Millbrook Proving Ground, the demonstrated vehicles are being offered to meet the requirements of the UK MoD’s Land Mobility Programme (LMP) and specifically, the lighter General Support Utility Platform (GSUP) and Light Mobility Vehicle (LMV) requirements, expected to be selected in 2026.

Team LionStrike was announced in early September 2025 followed by the GM Defense GSUP vehicle being revealed on static display at the UK DSEI exhibition later that month (DSEI 2025: GM Defense Reveals New General Support Utility Platform).
Now, for the first time in UK, guests and media have had the opportunity to ride and drive and see all three variants up close and in detail. Demonstrated were three proven, Commercial Off-The-Shelf (COTS) light and utility military vehicles:
- GSUP – based on the Chevrolet S10 Work Truck, delivering capacity for 4 crew, flexible and modular cab/utility configurations, 207HP diesel, and a payload of 1116 kg.
- Silverado 1500 ZR2 – a light duty, more powerful variant delivering capacity for 5 crew, flexible and modular cab/utility configurations, 305HP diesel, and payload of 705kg.
- Infantry Squad Vehicle-Utility (ISV-U) – based on the Chevrolet Colorado ZR2 platform, delivering capacity for up to 5 crew, open-top utility and tactical configurations.
All three demonstrated vehicles are backed by Team LionStrike, that is focused on offering the UK MoD a mobility solution to rapidly modernise its wheeled vehicle fleet. Team LionStrike will deliver economic growth as part of the Land Industrial Strategy, and significant export growth potential. Team LionStrike is building a sustainable supply chain and delivery ecosystem in the UK. LionStrike will be supported by GM’s leading UK team members, NP Aerospace and BAE Systems and is also anchored by GM’s worldwide parts distribution system.
J.D. Johnson, vice president of GM Defense Government Solutions and Strategy, said it was an “honour” for GM Defense and its U.K.-based LionStrike team members to demonstrate their COTS-based platforms at Millbrook to invited guests.
I truly believe that what makes Team LionStrike different is the fact that GM, with our history and proven capability, is embedded into the procurement and support solutions offered here, as the vehicle Original Equipment Manufacturer (OEM), Johnson said. Having the OEM so intimately involved provides capability, efficiencies and crucial assurance, confidence and support to the U.K. Armed Forces, through life.
Johnson added that the company is very proud of what our Team LionStrike strategy and plan will bring to U.K. industry, U.K. economy and potentially, future U.K. exports. He concluded by drawing a line from history to the present: As we’ve prepared for this event we have been able to look back and note with pride the level of support and involvement Chevrolet and GMC trucks played in the British military campaigns dating back to World War II. That successful heritage firmly underpins what we’ve been demonstrating here today.
