THE ROK AND USA COMPLETES ITS COMBAT PREPAREDNESS EXERCISE NORTH OF SEOUL–AS BOTH ARMIES FIELDED TANKS (K1A1, M1A1), ATTACK HELICOPTERS (AH-1S, APACHE, TRANSPORT (K-21, BRADLEYS, MLRS), SPECIAL FORCES, ARTILLERY (PALIDEN HOWITZERS), JET FIGHTERS (K15, F4, A-10)

The atmosphere was tense around the Seungjin Army Training Center in Pocheon, north of Seoul, Monday, before South Korea and the United States' large-scale joint live-fire exercise.
Some 3,000 spectators, including the public, journalists and soldiers from the two nations, made little noise while waiting to watch the military exercise at a time when tension was high on the Korean Peninsula.
Tension was heightened in the wake of North Korea's Aug. 4 landmine explosion inside the Demilitarized Zone (DMZ), which maimed two South Korean soldiers.
The exercises have taken place four times this month. President Park Geun-hye observed the last one held on Friday.
