This is actually something General Sharp has emphasized before:

American forces may have to focus the counterinsurgency skills they have gained in Iraq and Afghanistan on the threat posed by North Korea.

The American general leading US forces in South Korea told the South Korean military this week that “our enemies” are beefing up their guerilla warfare capabilities and would likely use improvised explosive devices and similar tactics if a ground war broke out.

Gen. Walter “Skip” Sharp said that means the South Korean military should prepare by conducting as much realistic training as possible – likely with the aid of the US.

“I believe we will face IEDs and insurgent forces in addition to large conventional attacks,” said General Sharp in remarks there Tuesday. “We must immediately begin preparing both ROK [Republic of Korea] and US forces to improve our capabilities in these areas.” Sharp didn’t mention the “thinking enemy” by name until the end of his prepared remarks. “North Korea is watching and I am convinced that discussing and demonstrating the strength, capabilities, and leadership of the ROK army is the best deterrence.”  [Christian Science Monitor]

I think General Sharp is on the right track with his thinking, but instead he should be examining the lessons learned from DMZ War period in the late 60’s instead of an all out invasion.  I have featured a number of these conflicts from the DMZ War here on the ROK Drop to include by far the largest and most provocative the Blue House Raid.

I have always felt that if the North Koreans felt like they needed to respond to lets say their missile site being bombed they would retaliate by infiltrating small teams to ambush soldiers on the DMZ, set up IED’s, or launch terrorist attacks within South Korea. For example just think about how easily North Korea could have some agents set up a few roadside bombs along MSR1 to hit a convoy of soldiers with?

In my opinion every leader in USFK would do well to read Daniel Bolger’s, Scenes from An Unfinished War: Low Intensity Conflict in Korea, if they are looking for ideas on what soldiers stationed in Korea should be training for.
