US Army Tests New SGT STOUT Air Defense System in NATO’s Formidable Shield 2025

Soldiers from the US Army’s 5th Battalion, 4th Air Defense Artillery Regiment (5-4 ADAR) recently deployed to Norway for NATO’s Formidable Shield 2025, where they successfully tested the Army’s newest short-range air defense platform, the SGT STOUT, in a series of live-fire engagements inside the Arctic Circle.

The SGT STOUT system, mounted on a Stryker vehicle and armed with Stinger missiles, a 30mm cannon, and onboard radar, fired its first Stingers in a NATO exercise. Soldiers engaged multiple aerial targets, including low-flying drones, in joint scenarios designed to simulate real-world threats. In one key instance, a crew dismounted and fired a Stinger manually when the vehicle system failed to lock on — demonstrating flexibility and battlefield readiness.

The exercise featured 16 warships, 27 aircraft, and eight ground units from 11 NATO and partner nations.

US and Norwegian SHORAD units served as the final air defense layer on Andøya Island, complementing ship-based and high-altitude interceptors. The integrated defense architecture allowed all NATO participants to share a common operating picture via data links, improving threat detection and response times.

Norwegian forces fielded their NASAMS (National Advanced Surface-to-Air Missile System) and Mobile Air Defense Systems, while US Marines supported with shoulder-launched Stingers and coordinated airspace via tactical operations centers.
