A new U.S. Marine Corps unit designed to fight in shadowy gray zones is getting its first real test in the Arctic, where NATO is honing its response to potential aggression in the High North.
The Corps’ new Multi-Domain Task Unit brings specialized intelligence and cyberwarfare capabilities to the alliance’s new Arctic Sentry mission focused on increased allied vigilance in the region, Marine Forces Europe and Africa said in a statement Thursday.
Maj. Gen. Daniel Shipley, commander of MARFOREUR/AF, said the debut of the unit in the ongoing exercise Cold Response in Norway centers on giving commanders advanced capabilities and necessary information before a conflict starts.
“It’s about creating a force that can act decisively at a moment’s notice, and much of that happens in the information environment,” Shipley said.
Ranging from signals intelligence and reconnaissance to cyberdefense and joint targeting powers, the unit’s capabilities can supplement and enhance those of other NATO forces in the region, the statement said.
Maneuvering in what’s termed the gray zone has been an area of focus for the U.S. and allied militaries in countering Russia, which often uses tactics such as cyberattacks, disinformation and sabotage to gain an advantage without triggering a full-scale conflict.
The incorporation of the high-tech Marine unit in Arctic drills shows how the alliance is preparing for a potential fast-moving crisis in the increasingly strategic High North.
In February, NATO launched its Arctic Sentry mission to bolster its presence amid concerns about Russian and Chinese activity in the region. Cold Response, hosted by Norway, is operating in conjunction with the broader the NATO effort.
Both the Marine Corps and the Army have been focused on developing multidomain teams in recent years. Such units specialize in gathering intelligence and disrupting adversaries in ways that help commanders see the shape of the battlefield before fighting even begins.
Should a crisis escalate, the Marine unit is designed to integrate directly with a larger Marine Air-Ground Task Force, MARFOREUR-AF said.
Its presence at Cold Response marks “a milestone” for the Marine Corps modernization efforts, the statement said, adding that it enhances the service’s ability to field forces capable of winning in the gray zone.
