So if you send you entire Army to Korea.....you're gonna open up a huge Can of Whip Ass and give them a proper thumping are you?
How long will it take you to get there, set up, establish your logistics tail, and be prepared to fight?
North Korea’s regular army consists of 4 corps in the front area, 8 corps in the rear area, one tank corps, 5 armored corps, 2 artillery corps, and 1 corps for the defense of Pyongyang, a total of over 80 divisions and Brigades. Almost all of these forces are based near the DMZ and require little time to be ready for an offensive. In fact because the North Koreans maintains these forces on a continuous state of alert there will likely be little appreciable warning before a commencement of hostilities.
