Notably, this marks the first instance of our military employing artillery in the maritime buffer zone since the signing of the inter-Korean military agreement on Sept. 19, 2018.

Instance
When a missile fired by North Korea crossed the Northern Limit Line (NLL) in the East Sea, our military deployed a fighter jet and fired three air-to-ground missiles into North Korea's high seas. This is the first occasion on which our military took direct action by firing into the maritime buffer zone.
