Interdiction

[Liquid_Sky]

So I have been trying to wrap my head around interdiction.

The rule book is a tad vague as to the mechanics.

I suspect that the way it works is...every time a unit moves a hex, a die roll is made. This is compared to the value in the Parameter data...say 45%. I imagine that this is for a unit at full road movement stacking...say 350 guys.

It is then adjusted somehow for units that are larger/smaller then this as I notice through experience that small units are hit far less then big units.

I guess that its prorated, so a unit at 700 would be double 45% and a unit at 175 would be 22.5%

If the die roll is a success, the game then picks a random available? /all? aircraft from the other side's list and launches an attack with it. The value of that attack is multiplied by the Parameter data interdiction effect. Say 20%. The defending unit gets no protection and is in travel mode.

So for a game like Normandy..where the units are moving from the bottom of the map up...travel about 100 hexes to reach the front line. A small unit of 4 guns will be hit (40/350)*45 = about 5 times. A single gun will be hit about once.

Note that speed doesn't matter...it just means more checks per turn since every hex is evaluated as the unit moves.

That is my understanding of it anyways...I could be wrong.

I also notice that when visibility is lower, interdiction seems to hit less. So it probably multiplies in the chances as well..probably the parameter data for Air Limitation: say 10% at 2 visibility, 25% at 3, 50% at 4 and 100% at 5...

....so the chance to get hit when visibility is 3 would be 45% * 25% or 11.25%.
