SEOUL, South Korea — Soldiers, tanks and other equipment from the new U.S. rotational brigade began arriving in South Korea on Thursday despite coronavirus concerns, with all arrivals required to undergo testing and a two-week quarantine.

The Fort Stewart, Ga.-based 1st Armored Brigade Combat Team, 3rd Infantry Division, is the ninth rotational brigade to serve with U.S. Forces Korea since the system began in 2015.

The Raider Brigade replaces the 2nd Armored Brigade Combat Team, 1st Infantry Division, which began deploying to the divided peninsula shortly before the pandemic began to take hold.
