WASHINGTON -- South Korean and American troops on and near the Demilitarized Zone separating North and South Korea are ready, well-supplied, well-trained and prepared, the senior enlisted advisor to the chairman said following a visit over the weekend.Army Command Sgt. Maj. John W. Troxell accompanied his boss, Marine Corps Gen. Joe Dunford, the chairman of the Joint Chiefs of Staff, to South Korea. But while the general participated in the Military Committee Meeting and Security Consultative Meeting with his Korean counterpart, Troxell used his time to get a feel for what life is like on "Freedom's Frontier" in light of current tensions.The DMZ is a place where North Korean troops are studying every action on the southern side. They continually probe, test and push for a reaction from the South Korean troops that man most of the DMZ.The unit Troxell visited -- the 1st Republic of Korea Division's 1st Reconnaissance Battalion -- was the victim of a North Korean intrusion across the DMZ three years ago and had soldiers wounded in a minefield laid by North Korean special operations forces.UNFILTERED LOOK AT THE NORTH"I felt the need to go up to the Demilitarized Zone outside of the Joint Security Area and go to an area where I could get an unfiltered look at the North Koreans and what their demeanor, what their disposition, what their posture was in light of all of this rhetoric," Troxell said.He also just wanted to talk with South Korean troops to get a feel for their morale and readiness, he said.The sergeant major's previous job was as the senior enlisted leader for U.S. Forces Korea and the Combined Forces Command.He said he did not notice much difference in the North Koreans across the line. "They were on security," he said. "They were observing into the South, especially when I got there -- a lot of folks with binoculars trying to figure out what we were doing. But their patrols did not seem like they were in any more enhanced readiness than what they normally are."Despite the rhetoric from North Korean leader Kim Jong Un, the North Koreans were carrying on business as usual, he said. On the North Korean side, there are heavy weapons in contravention of the U.N.-brokered armistice signed in 1953. The North kicked out the two armistice guarantor nations -- Poland and Czechoslovakia -- when the Soviet Union fell."We still have the Swiss and the Swedes in the southern part of the DMZ that are making sure that the [South Koreans] and the U.S. aren't breaking any rules, in accordance with the armistice," the sergeant major said.The assumption in the south is that the North Koreans are breaking the rules and allied forces have to plan accordingly, he said.'FRAIL' TROOPSAnd there are a lot of North Korean troops. "There's 750,000 North Korean troops on the DMZ, out of a more than 1.1 million man and woman force," Troxell said. "But we haven't seen them do a combined arms maneuver in 20 years. They fire about five to 10 rounds out of their rifles a year. And a good part of them have been diagnosed as being medically frail.""But there are 750,000 of them," he continued. "So if you end up in conflict and you got full magazines of ammunition, you better not miss."And the North Koreans have been indoctrinated since birth on the infallibility of the Kim family. "If we have to go into high-end conflict, the North Koreans are going to fight," Troxell said. "They're prepared to fight and defend their country and defend who they call the Great Leader."On the South Korean side, the troops were patrolling and ready, the sergeant major said. They are a learning army, he said, and have learned from the incident where the infiltrators came in. "They've really upgraded their positions," Troxell said. "They've cut back all of the foliage from around their guard posts and the gates to get into the DMZ. They've also reinforced with, you know, better cameras and everything, so they have [fewer] blind spots that the North Koreans can exploit."'READY TO FIGHT'A bit farther back, the sergeant major met with American Soldiers. "Obviously, they pay attention a lot more to the news than the [South Koreans] do, and certainly more than the North Koreans," he said. "There was a lot more heightened sense of, 'Hey, we got to be ready.'"The rotational brigade -- now from the 1st Cavalry Division -- goes through a decisive action training rotation at the National Training Center in California and then deploys to the Korean Peninsula. "Those guys and gals are absolutely prepared for high-end conflict because they've been certified in it," Troxell said. "They're ready to fight."American units are training and focusing on potential threats, one of which is North Korea's use of tunnels. "Subterranean warfare is something we have to continue to prepare for," the sergeant major said. "As a matter of fact, the Army is making subterranean warfare part of their doctrine, and the Marines are going that way too."South Korean and U.S. soldiers serve together closely. The 2nd Infantry Division, which is the divisional headquarters there, is now a combined division, with South Korean and U.S. officers and noncommissioned officers on their division staff. "If you look at the 2nd Infantry Division patch, … it says combined division over their patch now," he said.The 2nd Infantry Division is also certified at all levels of combat.BUILDING MIL-TO-MIL RELATIONSHIPSThe members of the division continually look for ways to enhance the military-to-military relationship, Troxell said, especially in their noncommissioned officer corps. The South Koreans are looking "to better develop their squad leaders and platoon sergeants to operate effectively at the decentralized level and operate off of commanders' intent and apply discipline initiative to get after combat, if they have to," he said. "They really look at the noncommissioned officer corps in the United States military, and they want theirs to be like that."There are cultural differences that have to be overcome and much of the South Korean military is made up of conscripts. But, South Koreans have served alongside the U.S. in every contingency since the Korean War, Troxell said, and they see that the American military expands the commander's reach in the battlespace by empowering noncommissioned officers to act without being told.This is especially needed in terrain like that at the DMZ, which is mountainous. "It's a cluttered battlefield," he said, "and it will call for decentralized execution to defeat the North Koreans. That means we've got to continue to have empowered enlisted leaders, because this will be a squad-level fight, more so than it will be a battalion/brigade-level fight."
