American Soldiers who specialize in chemical, biological, radiological, nuclear and explosive hazards joined forces with South Korean troops during Exercise Key Resolve in South Korea.

Soldiers from 20th CBRNE Command (Chemical, Biological, Radiological, Nuclear, Explosives) built on their long-established relationship with the Republic of Korea (ROK) Army Chemical, Biological and Radiological Defense Command during the annual exercise.

Defensive in nature, Exercise Key Resolve was conducted from March 2 - 12 to keep American and South Korean forces ready to maintain security on the Korean Peninsula and stability in Northeast Asia.

In support of the 20th CBRNE Command's regional alignment efforts, the Fort Carson, Colorado-based 71st Explosive Ordnance Disposal Group trained with the 2nd Infantry Division during the exercise. Personnel from the 20th CBRNE Command Headquarters trained with Eighth Army, the U.S. Army's top operational command in Korea.

A one-of-a-kind formation that serves with allied, interagency and joint partners around the world, the Aberdeen Proving Ground, Maryland-based 20th CBRNE Command deploys for exercises in South Korea.

Soldiers from 20th CBRNE also trained with South Korean CBR troops at the National Training Center on Fort Irwin, California, during Exercise Atropian Phoenix in June 2014.

Col. Rich Schueneman, the 20th CBRNE Command chief of staff, said the allies forged an even stronger relationship during the two-week exercise.

"Our partnership with the ROK CBR Defense Command is an example of the strength of the U.S.-South Korea Alliance," said Schueneman, a Bristol, Indiana native, who served in the 1-72nd Armor Battalion in South Korea in mid-1990s.
