Next War: Korea – Seoul Train AAR

GMT’s Next War: Korea is part of the ongoing “Next War” series designed by Gene Billingsley and Mitchell Land.  The series is based on potential conflicts in the world today. The first release in the series, Next War:  Korea, was successful enough to keep the series going with the 2014 publication of Next War: Taiwan..  I can see why.

Next War:  Korea has gotten a lot of positive response from gamers over the last couple of years and it’s been well supported with updates, errata, and Land’s helpful responses to even minor questions over on BGG.  The rules are cleanly written and the units are nicely done with beautiful maps.  There’s a standard rule set and an advanced one with all the bells and whistles and tons of optional rules. The standard rules are not difficult to learn and they manage to incorporate the core concepts of a good wargame without feeling watered down.  The real meat of the game, so I’m told, is in the advanced rules – which I haven’t gotten into yet.

GMT’S Next War: Korea (2012)

In this first scenario for Next War: Korea, called “Seoul Train”, we’re using standard rules.  The DPRK has begun a surprise attack on South Korea and its intentions are to cross over the DMZ and grab Seoul as quickly as possible.  But this isn’t going to be a cakewalk like 1950. The DMZ is heavily fortified and the ROK is no pushover.  Fortifications at the border prevent the DPRK from using road movement in these zones and it’s an extra +1 movement point to pass through these hexes during the game’s first turn.  Add to this problem that the North Koreans only get 4 game turns (2 weeks) to grab Seoul and you’ve got a division-sized headache for any military commander bent on impressing Dear Leader.

The game starts out with the North Koreans having initiative (and keeping it for the next two game turns), which allows them to conduct extra movement and combat (exploitation movement and combat) after going through the standard movement and combat turns.  The scenario also allows the DPRK player the use of three tunnel markers, which allows for overstacking in attacking hexes and a -2 DRM on attacks directly across the border into the DMZ.  The North Koreans also get a couple of Mi-24 attack helicopters for close air support as well as some specialized elite units that can add to attack efficiency ratings or be used to sneak around ROK units and cause havoc in the rear areas.

Game Turn 1:

The North Koreans start off the war in clear weather with 2 air points while the ROK has no air points available for support this turn.  I guess the DPRK really caught the south with its pants down today!  In any case, the skies are still contested at this point.  It’s not enough of a difference (not even close, actually) to obtain air supremacy.

The NK player lands an airborne brigade to the east of Seoul in swamp terrain just outside of Uijeongbo after it survives air defense fire.  The brigade moves immediately to try and seize the northeast outskirts of Seoul and draws a clearing marker (in NW: K, you don’t just automatically grab control of urban hexes, you need to clear them out first).  This is a diversionary move meant to pull vital units to the south away from reinforcing the battle going on up at the DMZ.

The NK player uses three tunnel markers to attack several ROK hexes and, with the help of light infantry (especially the 17th Sniper Brigade, which can call in Mi-2 support), it takes all but the most eastern hex.  In the battles, one of the ROK AH-1 Cobras get called in for air support and was shot down by air defense fire.  The North Koreans also took losses with their Mi-24 Hind helos, but the unit is far from finished fighting.

NK airborne units seize Seoul and are placed under clearing marker.  

The only remaining survivor of the attacks is the ROK 5th Infantry Division from VII Corps (which has suffered a step loss) while the ROK Ist Corps has lost two full divisions.  The 101st brigade from Ist Corps huddles in the corner of the fighting, surely to be targeted next for elimination in the exploitation phase.  The North Koreans have lost only a light infantry brigade so far.  The first round of the invasion can be considered an enormous success for the DPRK at this point.

DPRK advances after the initial movement and combat phase of GT 1.

In the elite movement phase, the non-initiative player (the ROK) gets to move its best units which are not in an enemy ZOC.  The Capital Mechanized Infantry Division, sitting in the south of Seoul, moves up to take on the DPRK’s 38th Airborne Brigade in hex 3021.  Since leg units get double defense values in urban hexes, the battle may not be so clear cut in terms of outcome.

Elite Reaction Phase:  Capital Mech. Div. moves adjacent to 38th DPRK Airborne, spoiling for a fight.
Exploitation movement and combat begins so the DPRK starts to shuffle around its units in the rear, placing two light infantry brigades on the eastern flank in a hopeful attempt to bypass the ROK units and get around into the ROK rear again.  The objective is just to sow more chaos in the South.  Meanwhile, the 101st ROK brigade is completely overrun near the border and the 5th division from VII Corps to the east is destroyed.  The North Koreans are pouring in everywhere and with no air to stop them, the south is getting hammered again and again.
The ROK 9th Division moves east to hex 2919 to try and help contain the flood.  It is placed just behind the front lines and right in the direct path of Seoul itself.  The Capital Mechanized Infantry Division assaults the DPRK airbone regiment in Seoul and both units are completely destroyed.  This is a huge loss for the ROK as a 10-11-8 unit has just been wiped out by a 2-2-5 one.
During the reinforcement phase, the Americans enter the scene and a mechanized brigade from 2nd Infantry Division arrives northeast of Seoul.  Two AH-64 Apache units are based in Incheon for close air support.  
Reinforcement Phase:  Turn 1 – US Army’s 2nd ID arrives to help defend the capital.

Things aren’t completely lost for the South Koreans.  The NK advances have mostly stopped short at the Han River and the arrival of reinforcements could certainly help shore up the defenses.  On the other hand, the extra MP cost for moving through the DMZ fortification hexes will be gone in the next turn, which will certainly keep the ROK busy with units moving steadily south.

Game Turn 2:

Just when you think things couldn’t get too much worse for the ROK, along comes a storm and grounds their entire air force.  The DPRK’s air force is also grounded but it’s not like it was doing much anyways.

The movement phase starts off with North Korea sending its light infantry on the eastern flank down south through the DMZ.  Controlling these hexes enables follow on units to use road movement so this helps out considerably when a couple of divisions north of the DMZ punch down to join the growing push in this area.

DPRK light infantry brigades clear the DMZ hexes on the right so follow-on heavier units can take the road.

In the combat phase, the North Korean player has two options – either to push on to the eastern flank and hit the 20th ROK Mech. Inf. Division or try for some riskier attempts closer to the coast.  Undoubtedly the terrain to the west is a little easier to deal with than the highlands hex where the 20th now sits.  But it seems that DPRK can bring much more strength to bear on the 20th and taking out this ROK unit before the Americans arrive at the front would be most helpful.  So the DPRK attacks at 3:1 odds and trades a step loss with the South Koreans, who nevertheless stubbornly remain in the hex.

The Americans move their unit from the 2nd ID stright north to Uijeongbo in the elite reaction movement phase to firm up the ROK’s right flank.

During the exploitation movement phase, the North Koreans replace some light infantry lost in the fight against the 20th and send another light infantry unit down into the DMZ to keep clearing the path to Seoul.

During the exploitation combat, the DPRK decides to hammer away again at the 20th ROK Mech. Inf. Division in an attempt to finish it off.  With a -2 column shift on the CRT, this will be riskier than last time even though the 20th has already taken a step loss.  Fortunately, for the North Koreans, they manage to destroy the 20th after taking two step losses and advance a stack of attacking units from north of the Han straight into the highlands hex.  As a bonus, they also capture an ROK airfield in the hex.

North Korean armor and mech infantry advance south   ROK units move up HQs to help with defense.

The ROK is in a real panic now.  Moving its stronger units from the west would mean inviting an attack on the left flank that would bring the North Koreans within easy reach of Seoul.  In desperation, the South Korean player brings up some HQ units to add a meager amount of defense to help out the crumbling right flank.  It seems obvious the DPRK is going to hit hard in the next turn so the idea of gambling a loss by counterattacking north is out of the question.  The only thing that might save the ROK next turn is air – and lots of it.

Game Turn 3:

The storms continued unabated into the second week of the war.  North Korean light infantry continued their advance along the ROK right flank and headed into the city of Namynangju.  Now the North Koreans had effectively bypassed the front lines and had infiltrated into the ROK’s unprotected rear.  Nothing lay between these advance units and Seoul.

Turn 3 Movement:  NK forces push their light infantry past the Americans and towards Seoul.

The first combat phase for the North Koreans was full of possibilities.  The American unit in Uijeongbo was the obvious next target for the DPRK but the defender’s terrain was unfavorable to armor river crossing and an uphill battle into the city.  It was time to dent the ROK line further to the west and gain some breathing space for the DPRK units in the center of the front line.

The ROK 2nd Armored Brigade and 25th Infantry Division of I Corps stuck out like a sore thumb in hex 2918 and the rough woods terrain was great hunting ground for the DPRK light infantry massed to the north and northwest.  The attack wasn’t totally without risks.  Crossing the mighty Han River during a storm would be no piece of cake but the DPRK units managed to eliminate both ROK units in one fell swoop without taking any step losses in return.

DPRK units advance into hex 2019.

The ROK was completely shattered at this point.  A lone HQ unit sat in desperate defense between two mechanized divisions and the Americans held on to the right flank – but just barely.  Not wanting to further risk losing their momentum, the DPRK held back during the exploitation phase but did move a light infantry unit south into Namynangju to assist its comrades with clearing the city.

Flipping over the clearing marker, we get a “3”, subtracted from the efficiency rating of the light infantry (6) for a +3 DRM.  Since we’re one unit under the minimum safe stacking number,  there is a -1 DRM applied to the roll.  All we need to do is get a “1” or greater on the roll and the city is cleared.  The roll comes up a “0” and the city is not cleared.  One of the light infantry units is destroyed.

DPRK light infantry units in the south fail to roll equal or greater than the clearing number and take a step loss.

This could actually work very badly against the DPRK.  Next turn is a contested turn, which means that exploitation movement and combat will not happen.  This really limits what the North Koreans are able to do.  Best case scenario at this point is grabbing a single hex in Seoul for a minor victory.  I’m kicking myself for not getting more light infantry on the right flank moving faster down into Seoul earlier in the game.

Game Turn 4:

More storms!  Both air forces have been grounded for more than a week now as each side slogs it out in the rain and mud near the DMZ.  Since this is a contested game turn, I decided to go for broke here.  My DPRK light infantry unit bypassed Guri without clearing it and went right through to Seoul, hoping to capture it by the end of the turn.  A clearing marker is placed on it.

DPRK light infantry in the heart of Seoul placed under clearing marker.

Meanwhile, I decided to just go for broke with the units I had at the front and try to destroy the defending ROK army units.  Successfully doing so would shift victory one level further in DPRK favor, leading to a major victory.  The DPRK attacked all three ROK units but destroyed none of them.  They each took a step loss after inflicting heavy damage on my DPRK divisions.

The 30th ROK Mechanized Infantry Division near the border took a step loss along with a divisional HQ unit in hex 3019.  The lone ROK headquarters unit defending in the middle of the pack lost a step and was forced back south towards Seoul.  The attacking DPRK infantry units were only too happy to advance one hex after combat with only one hex between its new position and South Korea’s capital.

DPRK punches a hole right in the middle of the front by the end of combat at turn 4.

The ROK units were forced to pull back and form a new line of defense around the northern outskirts of Seoul.  The frontlines were extremely brittle but they held – for now.  The only remaining thing to do was to check if the DPRK could squeeze a victory out of the scenario by controlling a hex of Seoul.

Checking for hex control at the end of turn 4.

We get a “5” on the back of the clearing marker and this gives us a +1 DRM for the clearing attempt.  Unfortunately, we only have 1 stacking point and the minimum safe stacking points for an urban hex is 4.  This means a -3 DRM for a total of -2 DRM for the clearing check.  We roll a “1” and curse, as the clearing attempt fails and the unit is removed from the map.

The final result is a Minor ROK victory, according to scenario rules.  This is actually the best result I’ve had yet with the DPRK.  One thing I’ve learned is that the North Koreans need to use their light infantry to make repeated infiltration attempts from the first turn and get as many units as possible into Seoul.  The ROK military might be too powerful to totally overwhelm and punch through in enough time for a win.  There were so many situations in this game that made infiltration a perfect option for the DPRK.  First there were the tunnels in turn 1, which allow for automatically successful infiltration attempts.  Next, the storms give a favorable die roll modifier for infiltrating units.  It looks like my efforts may have been too little too late.  Perhaps I also could have just focused more on the ROK right flank with the DPRK attacks in turn 3.  A very successful attack would have also opened the road to Seoul.

Update:  Made some mistakes here with movement of light infantry and going a hex or two beyond the play area.  I also didn’t follow the complete phase order.  No wonder things were so tough for the North Koreans!  Anyways,  I’m replaying again with the correct rules now and finally using those precious airmobile units to full effect!  I’ll rewrite another AAR later so you can get a more accurate picture of the game.


  1. I lived in Goyang (spelt Koyang when I was there in 1996-99) Always annoying as you never knew if the gunfire heard at night was the guys practicing, or the North sending Commandos down.
    Their DUI checkpoints are manned by tanks and full squads of troops, with the GPMG gunner aimed at the driver of the vehicle to their front!

  2. Thanks Mark! There's a combination of reasons I haven't been posting lately – it's basically just work and my wife and I preparing for the arrival of a baby soon. Work has finally – finally calmed down after a month and I'll be posting again very soon. Thanks for all your support and the mention!
