SEOUL, The U.S. Forces Korea (USFK) conducted an exercise last week to improve the operation of a THAAD missile defense battery deployed to South Korea to better defend against North Korean missile threats, officials have said.

The weeklong exercise at Camp Humphreys in Pyeongtaek, some 70 kilometers south of Seoul, focused on reloading inert munitions in launchers of a Terminal High Altitude Area Defense (THAAD) battery, according to the officials.

The exercise was led by service members of the 35th Air Defense Artillery Brigade. It coincided with North Korea's test-firing last Wednesday of what it claimed was a "new-type tactical guided weapon."

"The exercise allowed the D-2 THAAD to showcase crew proficiency and readiness," the brigade said in its recent Facebook posting.

Last year, Seoul and Washington installed the THAAD system here aimed at countering North Korea's missile threats, with the two sides saying the deployment is "temporary."
