Seoul Train
This scenario represents the NKPA drive south from Kaseong on Seoul. It uses only a portion of the map and units and has special Victory Conditions.
The North Korean People's Army (NKPA), taking advantage of the fact that Zones of Control (ZOC) don't extend across the DeMilitarized Zone (DMZ) on Turn 1 and Tunnels (in hexes 2718, 2818, and 3017) allow overstacking , moves to setup its attacks in the Initiative Movement Segment. Notice the successful Air Assault (Airmobile Movement) and Paradrop (Airborne Movement):
Initiative Combat Segment:
The NKPA attacks all across the front as follows [note these are not, necessarily, optimal attacks]:
1. The NKPA II Corps attacks the Republic of Korea Army ROKA 5/VI Infantry Division (ID) in 3017. Initial odds are 23:8 which reduces to 2:1. Odds shifts left two because the defender is in a DMZ hex to 1:1. The odds shift right one because of Surprise, a Scenario Special Rule (SSR), to 1.5:1. They shift an additional column right due to the Efficiency Rating (ER) differential: the NKPA chooses the Light Infantry (LI) Bde. (ER=6) while the ROKA must choose the 5/VI ID (ER=5). So, the final odds are 2:1. The NKPA chooses not to commit any air or helicopter support. The ROKA successfully commits an AH1, so the NKPA incurs a +1 DRM. The defender is in a DMZ hex which incurs another +1 DRM. The initial odds remainder (division with a remainder) earns the NKPA a 1 DRM. An attacking LI unit earns a 1 DRM. Additionally, the Tunnel placed in 3017 earns another 2 DRM. The final DRM is 2. The die roll (DR) is a 3, modified to 1, crossreferenced on the Rought Woods row resulting in /1R. The defender takes a step loss and must retreat. However, since the defender occupies a Fortification hex (the DMZ) it can roll lower than or equal to its ER in order to ignore the retreat and does so (with a roll of 2).
2. The NKPA 8/II ID attacks the ROKA Combat Outpost across the river in 2917. The 8 ID's attack strength is halved for attacking across the river, so the Initial Odds are 4:2 or 2:1. Two left (DMZ) brings it to 1:1; one right (Surprise) makes the odds 1.5:1. Since the ER's are the same, there are no additional column shifts. DRMs are as follows: +1 (DMZ), 1 (NKPA Air Support) for a net +0. The DR is an 8 crossreferences on the Marsh row, resulting in a 2/1. The Combat Outpost destroys the river crossing division, but is eliminated in the process.
3. The NKPA 815th Mechanized Corps attacks the ROKA 1/I in 2818. Initial Odds are 25:8 which reduces to 3:1 with a remainder. Odds shifts are as follows: 2L (DMZ), 1R (Surprise), so Final Odds are 2:1. DRMs are as follows: +1 (DMZ), 2 (Tunnel), 1 (Odds remainder) for a net 2. The DR is a 9, modified to an 7, crossreferenced on the Rough Woods row results in a 1/1. Both sides take a step loss.
4. The final attack involves elements of the NKPA IV Corps attacking the 101st Bde in 2718. Initial Odds are 7:2 which reduces to 3:1. Odds shifts are as follows: 2L (DMZ), 1R (Surprise), 1R (ER) for Final Odds of 3:1. DRMs are as follows: +1 (DMZ), 2 (Tunnel), 1 (LI), 1 (Odds Remainder) for a net 3. The DR is a 2, modified to 1, crossreferenced with the Rough Woods row results in /2R. The 101st is eliminated.
Here's the situation following Advance After Combat:
Elite Reaction Segment:
Even though the NKPA Airborne and Sniper bdes don't possess ZOCs, they are sitting astride the main reinforcement roads for the ROKA VII Corps (only ER 6+ units can move in this segment) units in Seoul forcing them to attempt to move through the Highlands to get to the battlefield:
Exploitation Movement Segment:
The NKPA, in this segment, moves any units not in an enemy ZOC. Note, LI units ignore ZOC in nonFlat terrain. Also, notice that the NKPA 38th Abn Bde successfully rolled against the Advance/Control Check to enter the City hex in 2821:
Stay Tuned!

Exploitation Combat Segment:
Note that the NKPA wants to choose its attacks carefully in this segment as there's an automatic additional two column shifts left on the CRT for attacking in the Exploitation Combat segment.
1. The NKPA II corps will renew its attack on the reduced ROKA 5th ID. This unit is a pain in the NKPA's side as, by SSR, it must maintain units adjacent to the 5th as long as it remains in its starting hex. Initial Odds are 23:4 or 5:1 (with a remainder). Column shifts are as follows: 2L (Exploitation), 1L (DMZ), 1R (Surprise), 2R (ER) for a final of 5:1. DRMs are as follows: +1 (DMZ), 2 (Tunnel), 1 (LI), 1 (Odds remainder) for a net 3. Neither side commits any air or helicopter support. The DR is a 7, modified to 4, crossreferenced on the Rough Woods rows results in /1R. This eliminates the 5th ID allowing the NKPA units to advance. 2. Elements of the VI corps and the 815th Mech corps attack the reduced ROKA 1 ID. Initial Odds are 40:4 or 10:1. Since the maximum odds column for Rough Woods is 7:1, the Initial Odds are reset to 7:1 but the NKPA earns a 1 DRM. Column shifts are as follows: 2L (exploitation), 1L (DMZ), 1R (Surprise), 2R (ER) for a final 7:1. DRMs are as follows: +1 (DMZ), +1 (NKPA multicorps attack), 1 (LI), 1 (3+ hexes attacking), 2 (Tunnel) for a net 2. Neither side commits air or helicopter support. The DR is a 2, modified to a 0, crossreferenced on the Rough Woods row results in /3R. The 1st ID is eliminated, allowing the NKPA to advance. Here's the situation after Advance After Combat:
Reaction Movement:
The ROKA finally gets to move all its units and attempt to shore up the holes in its lines. They'll also move so as to be able to attempt to eliminate the pesky LI brigades running around in their rear:
Reaction Combat:
1. The Capital mech. Div. attacks the 17th Sniper brigade. Initial Odds are 9:2 or 4:1 (with a remainder). Column shifts are: none. The NKPA successfully commits helicopter support for a +1 DRM; the ROKA helo aborts. DRMs are: +1 (defending LI), +1 (helo), 1 (Odds remainder) for a net +1. The DR is a 4, modified to a 5, crossreferenced with the Highland row results in 1/1R. So, the Capital division takes a step loss and advances, and the 17th is eliminated. 2. The 9th ID and 2nd Arm Bde of the ROKA I corps attack the 38th Abn Bde. Initial Odds are 12:2 or 6:1. Column shifts are 1L (ER), 2L (City) for a final 3:1. Both sides' helicopters abort. DRMs are +1 (defending LI) for a net +1. The DR is a 0, modified to a 1, crossreferenced with the Rough Woods row results in 1/2R. Normally, the ROKA would take a step loss, but, since the NKPA cannot fulfill its entire step loss requirement (the LI only has a single step), the ROKA losses are reduced by one. The 8th ID advances into the City. Note that it does not require an Advance/Control check as it was a ROK city to begin with. Here's the situation after Advance After Combat: Now, since this was an Initiative Turn, we start the Basic Sequence which consists of a First Movement and Combat Segment (Initiative Player) and a Second Movement and Combat Segment (nonInitiative player).
First Movement Segment:
The NKPA moves all of its units again, in this case, reinforcing the dearly bought bridgehead across the river:
First Combat Segment: The NKPA now conducts any attacks it desires. The river severely limits the North's options, however, so he opts for a single attack on the powerful 20th Mech Div:
1. Initial Odds are 27:11 or 2:1 (with a remainder). Column shifts are: 2L (DMZ), 1R (Surprise) for a final 1.5:1. The NKPA commits two Air Points for support which arrive successfully; the ROKA commits its single Air Point which aborts. DRMs are: +1 (DMZ), +1 (multicorps attack), 1 (LI), 2 (Air Support) for a net 1. The DR is a 1, modified to a 0, crossreferenced with the Rough Woods row results in a /1R. The 20th loses a step and rolls against its ER to ignore the retreat result and fails:
Second Movement Segment: Now the ROKA gets a chance to move and address the whole suddenly punched in its line. The ROKA will not conduct any combat in the Second Combat Segment:
This concludes Turn 1.
The NKPA has breached the river line and can now bring its preponderance of strength to bear against the now compressed ROKA defensive line. Can the ROKA hold on and keep the North from taking Seoul?

Re: Seoul Train AAR  Part 3
Turn 2
Initiative Movement Segment
The NKPA has the Initiative, by SSR, for GT 1, 2, & 3 in this scenario, so we begin the turn with the NKPA Initiative Movement Segment. The NKPA moves so as to keep corps integrity as much as possible and set up attacks for the upcoming combat segment. Two LI brigades attempt an Air Assault (via Airmobile movement) to 2820, but one fails its Air Defense Fire (ADF) roll and is eliminated:
Initiative Combat Segment
The NKPA declares a single attack: the II and 815th attack the 25/VI ID and reduced 20/VII Mech. ID in 3019. Initial odds are 35:13 or 2:1. Column shifts are: 2L (DMZ), 1R (ER) for a final 1.5:1. Both sides commit a helicopter with the NKPA arriving and the ROKA aborting. The NKPA commits 2 Air Points and the ROKA commits one (which is all available for both sides). All the Air Points survive ADF. So, DRMs are as follows: +1 (DMZ), +1 (ROK Air), +1 (multicorps attack) 1 (odds remainder), 1 (NKPA Helo), 2 (NKPA Air), 1 (LI) for a net 2. DR is an 8, modified to a 6, which results in 1/1. The NKPA eliminates the LI (chosen as the Lead Unit for its ER), while the ROKA eliminates the already reduced mech inf. Div (chosen as the Lead Unit). Since the result did not call for a retreat that ends the combat segment and the NKPA is stalled for a moment:
Elite Reaction Segment
The only unit available for the ROKA to move is the Capital Division, and, since it's sitting in an enemy ZOC, it loses that ability. So, we move on to the NKPA
Exploitation Movement Segment
Since the NKPA didn't move any ROKA units out the way during the Initiative Combat segment, the only thing they do is move another LI brigade up to replace the one lost in that attack.
Exploitation Combat Segment
Taking advantage of the fact that the ROKA couldn't reinforce the hex, the NKPA attacks the same again. Initial odds are 35:8 or 4:1. Column shifts are 2L (DMZ), 2L (Exploitation Combat), 1R (ER) for a final 1.5:1. Both sides commit helicopters and both get hit with ADF (reducing the NKPA helo and eliminating the ROK helo). Neither side has Air Points available. DRMs are +1 (DMZ), +1 (multicorps attack), 1 (odds remainder), 1 (LI) for a net +0. The DR is an 8 resulting in 2/1. The NKPA loses the LI brigade and reduces on the mech infantry brigades. The ROKA reduces the 25th ID.
Reaction Movement
The ROKA reinforces the 25th ID with the 9th ID, debates the potential step loss for attacking the LI brigade and decides that it must to remove the threat from the rear.
Reaction Combat
Initial Odds are 22:2 or 11:1 which reduces to 6:1 (maximum odds in Flat Woods). Column shifts are none. Neither side commits helos. DRMs are +1 (Town), +1 (multicorps attack), 1 (odds remainder) for a net +1. The DR is a 7, modified to 8, resulting in /1R. The LI is eliminated, and the ROKA must advance a unit, choosing the 2 armored brigade.

Turn 2  Continued
Again, as this is an Initiative Turn, both sides get to perform Movement and Combat Segments in the Basic Movement and Combat Phase, Initiative Player first.
First Movement Segment
The NKPA doesn't have much in the way of movement, so the player moves on to combat.
First Combat Segment
Changing tacks, the NKPA player decides to try and expand the lodgment by attacking 2819 across the river with the IV corps along with the 815th Mech Corps.
Initial Odds are 34:11 or 3:1. Column shifts: 2L (DMZ), 1R (ER  there's a LI Bde hidden in the attacking stack) for a final 1.5:1. The NKPA has no air assets left, but the ROKA commits a helo which survives ADF. DRMs are: +1 (ROKA helo), +1 (DMZ), +1 (multicorps attack), 1 (odds remainder), 1 (LI attacking), 1 (3+ hexes attacking) for a net +0. The DR is a 9 which results in 2/1. The attritional battle continues.
Second Movement and Combat Segment
During the ROKA movement segment, the ROKA moves the 2 Arm Bde up to help defend the river line and wisely chooses not to counterattack anywhere.
This ends Turn 2 with the ROKA stubbornly holding the line and the NKPA striving to either break through or whittle the defenders down enough for the line to crumble.

Turn 3
This turn begins with both sides bloodied and the North Korean army looking imposing against a thinly held South Korean line.
Initiative Movement Segment
By SSR, the NKPA still has the initiative through Turn 3. Since they are constrained by SSR from moving further to the east (technically, southeast), there isn't much movement for them to do:
Initiative Combat Segment
Knowing that the ROKA units still holding out on the river are holding back the advance, the NKPA decides to concentrate on moving them out of the way.
Initial odds are 33:9 or 3:1. Column shifts are as follows: 2L (DMZ), 1R (ER) for a final 2:1. Both sides commits air points and helicopters with the NKPA helo aborting, the ROKA helo supporting the defense, and both sides air points providing combat support. DRMs are as follows: +1 (defender in Town), +1 (DMZ), +1 (Multicorps attack), +1 (ROKA helo), +1 (ROKA air point), 1 (NKPA air point), 1 (odds remainder), 1 (attacking from 3 hexes) for a net +2. The DR is a 4, modified to a 6, crossreferenced on the Marsh row resulting in 1/1. Both sides lose a step (from their Lead units).
Elite Reaction Segment is skipped since the only unit qualified by ER (the Capital division) is in a ZOC.
Exploitation Movement Segment
Keeping an eye on the ultimate goal of moving those ROKA units out of the way, the NKPA maneuvers to reinforce his attack. He also brings in some Light Infantry in an attempt to infiltrate the defensive lines.
Exploitation Combat
The NKPA player declares on another attack against the desperate defenders in Munsan.
Initial odds are 33:5 or 6:1. Column Shifts are as follows: 2L (DMZ), 2L (Exploitation combat), 1R (ER) for a final 3:1. Both sides commit helicopters, and the ROKA commits its last air point with both helos providing support and the air point aborting. DRMs are as follows: +1 (town), +1 (DMZ), +1 (ROKA helo), +1 (multicorps attack), 1 (odds remainder), 1 (Light Infantry), 1 (attack from 3 hexes), 1 (NKPA helo) for a net +0. The DR is an unmodified 9 crossreferenced on the Marsh row for a result of 1/. The NKPA attack fails miserably.
Reaction Movement and Reaction Combat are skipped as the ROKA player is simply attempting to hang on to the best defensive ground he can.
Now, we move in to the Basic Movement and Combat Phase.
First Movement Segment
The NKPA player is finally running out of units and starting to feel the attritional pinch. Nevertheless, more reinforcements pour in to attempt to force the river.
First Combat Segment
Once again, the NKPA player attacks across the river. Initial Odds are 34:5 or 6:1. Column shifts are as follows: 2L (DMZ) for a final 4:1. Neither sides has any helo or air support left. DRMs are as follows: +1 (town), +1 (DMZ), +1 (Multicorps attack), 1 (odds remainder), 1 (3 hex attack) for a net +1. The DR is a 1, modified to 2, for a result of 1/2R. Since the ROKA only has a single step loss to take, the NKPA reduces its step loss by 1 for an actual result of 0/1R. They've broken through.
Second Movement and Combat Segments
The ROKA will not attack, but they are now forced to withdraw and establish a new defensive line even closer to Seoul.
This ends Turn 3 with Seoul in danger but the NKPA rapidly losing steam from fighting through the DMZ.

Re: Seoul Train AAR  END
Turn 4 (Final Turn)
This turn begins with the North Koreans victorious across the DMZ and pressing the South Koreans who now have their backs up against Seoul itself.
This turn, by SSR, is a Contested turn, so there is no Initiative Movement and Combat Phase, so we skip to the Basic Movement and Combat Phase.
First Movement Segment
The NKPA follows up the retreating ROKA units and positions its forces for the final attacks.
First Combat Segment
In desperation, the NKPA will attack all across the line, splitting some of the stacked forces to provide better odds. The attacks will be conducted on the flanks first in the hopes of destroying the defenders and/or forcing them back so as to inflict serious loss on the Capital division in the division.
1. Vs. the (already reduced) 25th Inf. Division. Initial Odds are 16:4 or 4:1. Column shifts are as follows: 2L (defending in a City), 1R (ER) for a final 3:1. Neither side commits air assets. There are no DRMs. The DR is a 9 crossreferenced on Flat Woods results in a 1/1. The attackers may not automatically advance, however, because of the presence of the city (Goyang). They must first pass an Advance/Control Check which they do easily due to the modifiers for having additional units advancing as well as for causing the defenders to retreat (or, in this case, eliminate).
2. Vs. the 9th Inf. Division. Initial Odds are 21:8 or 2:1. Column shifts are as follows: 2L (DMZ), 1R (ER) for a final 1.5:1. Both sides commit helos, and the ROKA commits an air point. The NKPA helo survives ADF, but the ROKA helo is eliminated and the Air Point aborts. DRMs are as follows: +1 (DMZ), 1 (NKPA helo), 1 (odds remainder) for a net 1. The DR is a 3, modified to 2, crossreferenced with Highland results in 1/1R. Both sides lose a step from their lead units (in this case, the NKPA loses it's Armored Brigade) and the ROKA must retreat. However, as this is still a Fortified hex, it may attempt to avoid the retreat by rolling less than its (now reduced) ER. The 9th fails its roll and must retreat.
3. The final attack is against the Capital Division. Initial Odds are 15:11 or 1:1. Column shifts are as follows: 1L (ER) for a final 1:2. The NKPA commits its helo and an air point, and the ROKA commits its last air point. Once again, the NKPA helo and air point survive ADF, but the ROKA air point aborts. DRMs are as follows: 1 (odds remainder), 1 (helo), 1 (NKPA air point) for a net 3. The DR is a 3, modified to 0, crossreferenced with Highland for a result of 1/1R. Both sides lose a step and the Capital division while it may attempt to avoid the retreat (in a Highland hex) must retreat since it fails its ER roll. Since ZOCs do not project into Urban hexes, it retreats straight back.
This, effectively, ends the scenario, as there isn't much for the ROKA to do in its Movement and Combat segments. The result, by SSR Victory Conditions is a Minor ROK Victory as the NKPA controls no Urban hexes.
