U.S. Forces, Korea / Combined Forces Command Combined Ground Component Command (GCC)
US Forces, Korea (USFK) is the joint headquarters through which US combat forces would be sent to the CFC's fighting components - the Ground, Air, Naval and Combined Marine Forces Component Commands. Major USFK Elements include the Eighth US Army, US Air Forces Korea (Seventh Air Force) and US Naval Forces Korea. USFK includes more than 85 active installations in the Republic of Korea and has about 37,500 US military personnel assigned in Korea. Major U.S. units in the ROK include the Eighth U.S. Army and Seventh Air Force.
Principal equipment in EUSA includes 140 M1A1 tanks, 170 Bradley armored vehicles, 30 155mm self-propelled howitzers, 30 MRLs as well as a wide range of surface-to-surface and surface-to-air missiles, e.g., Patriot, and 70 AH-64 helicopters. EUSA has the capability to perform required tasks under various circumstances using this equipment.
US Air Forces Korea possesses approximately 100 aircraft: advanced fighters, e.g., 70 F-16s, 20 A-10 anti-tank attack planes, various types of intelligence-collecting and reconnaissance aircraft including U-2s, and the newest transport aircraft. With this highly modern equipment, US Air Forces Korea has sufficient capability to launch all-weather attacks and to conduct air support operations under all circumstances. In the event the Seventh Fleet and the Seventh Air Force Command augment them, the capability of USFK will substantially increase both quantitatively and qualitatively.
Analysts: U.S. pullback from DMZ not likely to undercut deterrence
South Korea has the misfortune of a capital that sits within range of hostile weaponry. Less than 40 miles separate Seoul from North Korean missile and artillery units stacked just north of the DMZ.
"Seoul is within range of 130 mm guns and 170 mm long-range self-propelled guns," Dunnigan said. "But the biggest killer would be long-range rockets, mainly the 240 mm ones."
M-1978 / M1989 (KOKSAN) 170mm self propelled (SP) gun
estimated at "40,000 m" to "over 50km"
24 miles / 40 km = extended range full-bore hollow-base (ERFBHB)
30 miles / 50 km = extended range full-bore base-bleed (ERFBBB)
35 miles / 60 km = rocket assisted projectile (RAP)
According to one report, a South Korean security analyst suggested that DPRK artillery pieces of calibers 170mm and 240mm "could fire 10,000 rounds per minute to Seoul and its environs." The number of Koksan guns is not publicly reported, but it is reliably reported that North Korea has about 500 long-range artillery tubes within range of Seoul, double the levels of a the mid-1990s. Large caliber self propelled artillery pieces typically have a sustained rate of fire of between four and eight rounds per minute. This suggests a total rate of fire of artillery alone of between 2,000 and 4,000 rounds per minute. The DPRK's two hundred 240mm MRLs fire either 12 or 22 rounds, providing a maximum single salvo of no more than 4,400 rounds.

These launchers can fire a first strike of many thousands of missiles and return in a few minutes to protected caves or to alternate firing positions. The MRLs move out from underground facilities (UGFs), fire from preplanned firing positions, and return to the UGFs. Examination of the available data on the UGF sites suggests that a number of possible exit and return methods for the MRLs may be possible. In this case, the launchers move directly from the firing points to the UGFs. This procedure makes it difficult to target the launchers, because once they fire it only takes 75 seconds to return to their UGFs. The MRLs can fire their complete set of rockets in 44 seconds. Data from the Joint Precision Strike Demonstration Project Office indicates that the crew then needs two minutes to lower the launcher, raise the stabilizing pads, and quickly return to the UGF. This gives a total exposure time of 164 seconds. However, it is possible that the MRLs could displace faster than the JSPD case or that they might take longer. [SOURCE]
Range estimate is only 35k though.
I wonder what the training level is on this, and how many of the sites are known and pre-targetted. Unfortunately, if the above information is correct, we only have 45-60 major artillery pieces, so nearly all would have to be done via air-power.
This is a set battlefield, so likely North Korea has a well-established and diverse comunications grid in place - though also likely we know precisely where the overwhelming majority of their fixed artillery pieces sit - especially the ones in deployed position. They have quite a number of mobile ones, but I wonder if they are very functional if they have been training to shoot-and-move.
American B-2's could take out the WMD's and major structures. A few dozen Tomahawk missles, launched ahead of the Navy fighters would hit the North Korean missle facilities and airfields.
After an hour or day of total shock and awe, American radio broadcasts messages urging surrender to the North Korean troops and leaders.
I don't think that the shattered military and starving populace would choose to die for Kim Jong-Il.
