Hello AmmoSgt,
thanks for your opinion about this.
I should have been more precise with my original question....
I'm trying to figure out what would be the effects on the *terrain* of a large (100X240?) SPWAW map.
The attacking player (US/USMC) would start on the southern edge of the map, the detonation would have taken place in the northern edge (around row number 40) of the map. This leaves 200 hexes from the starting location to the detonation. (= 10000 yards)
To prevent any misunderstandings:
The detonation would have taken place before the scenario begins
:)
The scenario would take place in March, 1946 (Operation Coronet, invasion of Honshu) or in November,1945 (Operation Olympic, invasion of Kyushu). The original plan for Olympic did not include the ABomb, but the plan was laid down in mid-1944 by people who where (at that time) not informed about the manhatten project (Nimitz, for example, learned about the bomb in February, 1945).
Later, it was suggested to use 3 bombs for each of the corps involved in the initial assault. 1 or 2 bombs (of each of these corps) would be used during the pre-invasion bombardment, the rest would have been used against japanese reserves.
This leaves two options for the scenario: A large (100x100) Map with the detonation in it's centre, the US/USMC starting on the edge and assuming that the detonation has taken place at least six-twelve hours earlier.
Or a giant (100x240) Map with a detonation that has taken place just a few minutes before the start of the scenario.
You suggested that a charge into a mushroom cloud would be difficult. This is true, but in 1945/1946 no one knew exactly how dangerous the radiation and the fallout is. But (nearly) everybody was aware that charging into a japanese held position was very dangerous ;) . Therefore, I think that it would be possible to convince soldiers that they had to hurry to exploit the hole created by the ABomb.
For the effects on the Japanese units exposed to the nuclear bomb:
It depends on the type of the unit.
According to "How to make War" (by James F. Dunnigan):
For a 20 KT detonation, a 50 % casualty rate will occur at a distance of
- 2714 Meters for troops in the open (~55 Hexes)
- 1900 Meters for troops in open earthworks (~40 Hexes)
- 1629 Meters for nonarmoured vehicles (~33 Hexes)
- 1221 Meters for armoured vehicles (~25 Hexes)
- 543 Meters for Heavy structures of concrete (~11 Hexes)
Therefore, closer to the point of the detonation there would be no infantry, but some Bunkers (very close to the detonation, there would of course be nothing).
The US troops (200 Hexes away) would be either in ships/amphibious vessels or at least in open earthworks. Therefore, they should be unharmed.
This would be the interesting aspect in SPWAW:
To have a scenario with very bad visibility, an enemy position that is hold by very few bunkers and some enemy infantry racing into the area to prevent you from assaulting the
weakened position...
So far, I hope that I have researched enough data to design the scenario. However, I simply have no idea how to create the effects of the Blast on the map (the terrain) :confused:. I tried it with black beach, but it looked not very convincing :(. If anybody here has an idea how to create a SPWAW map that includes blast effects from a 20KT-Nuke, please tell them.
By the way:
I know that the idea of writing a SPWAW scenario involving a tactical nuclear bomb sounds ridicoulus, but after a second look I have so far not found anything that would make it impossible...
I anyboby sees something that makes such a SPWAW scenario impossible, please tell me why you think so (I would hate continuing this idea and then learning that is is impossible because of XYZ). :)
