The U.S. Army and Republic of Korea forces fired missiles into the sea in a show of military power following a July 4, 2017 test launch of a North Korean intercontinental ballistic missile earlier that day.

According to the U.S. 8th Army, the snap exercise, “utilized the Army Tactical Missile System (ATACMS) and the Republic of Korea Hyunmoo Missile II, which fired missiles into territorial waters of South Korea along the East Coast. The system can be rapidly deployed and engaged. The deep strike precision capability enables the ROK-U.S. Alliance to engage the full array of time critical targets under all weather conditions.”
