The US Army and the Republic of Korea (ROK) Army have successfully conducted a live-fire exercise at Yeoncheon, South Korea.
The trials included firing a K55A1155mm self-propelled howitzer and the K9 Thunder 155mm self-propelled howitzer from 24 heavy artillery vehicles.
Nearly 30 guns hit targets simultaneously in the St. Barbara's impact area, which is approximately 6km from the demilitarised zone that separates North and South Korea.
Participating forces are members of the US Army's 1st Battalion, 82nd Field Artillery Battalion, 1st Armored Brigade Combat Team, 1st Cavalry Division.
Soldiers of the US Army joined forces with ROK soldiers from several battalions of the 26th Mechanized Infantry Division Artillery.
228th Field Artillery Battalion commander Lieutenant Colonel Jong Hwa Jung said: "By having an exercise together with US Army, not only can we reduce trial-and-errors, but also we can react to the situation promptly during war-time combined operations."
ROK previously partnered with 3rd Battalion, 16th Field Artillery Regiment, 2nd Armored Brigade Combat Team, 1st Cavalry Division for joint exercises.
In a separate development, South Korea and Japan will reportedly join the US for a joint anti-missile exercise in June.
During the exercise, the three countries will deploy Aegis destroyers to track missiles launched by North Korea.
The move forms a part of an agreement signed between the countries in 2014 to tackle nuclear and missile threats from North Korea, CNN reported.
