U.S. Army activates 3rd Battalion, 43rd Air Defense Artillery on Guam, replacing Task Force Talon

The U.S. Army has activated a permanent air defense battalion on Guam, replacing the task force that has guarded the island’s air and missile defense posture since 2013. Soldiers of the 3rd Battalion, 43rd Air Defense Artillery Regiment took part in an activation ceremony at Andersen Air Force Base on 16 October, according to an Army story published on DVIDS.

The battalion belongs to the 38th Air Defense Artillery Brigade, part of the 94th Army Air and Missile Defense Command. The Army describes the step as a move from a task force to a standing unit, and says it “cements” the Department of War’s commitment to permanent air defense capabilities in the Indo-Pacific.

From Task Force Talon to a battalion

Before the activation, air defense on Guam was the job of Task Force Talon, which began operating on the island in 2013. The Army says the task force operated the Terminal High Altitude Area Defense system, known as THAAD, which is designed to intercept ballistic missiles in the late stages of flight. It worked alongside other services and the Guam Army National Guard. Task Force Talon was deactivated in July 2026, the Army says.

The new battalion carries the lineage of the 43rd Air Defense Artillery Regiment, which the Army traces back to 1916 and to a predecessor organisation set up in the Philippine Islands.

What the Army says the unit will do

According to the Army account, the battalion’s mission is to support the defense of Guam by maintaining readiness and providing air and missile defense against potential threats, protecting the forces and infrastructure needed for joint operations across the region. Guam’s location, the Army says, makes it an important hub for those operations.

Col. Moseph Sauda, commander of the 38th Brigade, told the soldiers: “Your work here will never be ordinary. Your vigilance will have strategic consequences.” Lt. Col. Joshua Urness, the battalion commander, said the unit had helped turn “an ambitious concept” into operational capability by developing the procedures and links needed to connect sensors, command and control systems, launchers and interceptors. In his words, the battalion now “stands up the Army’s contribution to the strategic Guam Defense System.”

The Army story does not give the battalion’s strength, the list of weapon systems it will operate, or a date by which any new equipment will arrive, and those details are not confirmed here.
