11.616 says historical DRM do not apply to CPP, but 11.6161 says they do...which is it?
Those shown do.
How does one make a DR on the 11.618 weather table?
The weather is as shown on the chart. This is a vestige error.
Partial Orchards, 15.2 says they are not ? Terrain, however it is printed in red on the terrain chart...which is it?
The rule is correct at 15.2 (and in SmR at 10.2), the intent is the matches Partial Orchard as found elsewhere, eg PB/ABtF. Seoul Terrain chart should be black font there. The Smith's Ridge terrain chart has it correctly coded, for some reason not so on the Seoul chart.
On the terrain chart for “Factory”, in the comments column there is a reference to FFS8...there is nothing about factories in FFS8...why the reference?
This goes back to a time when the rules were all in one book. Xavier wanted the rules broken into three (all this briefly covered in the intro blurb on p.4), this was the old c-f to that first book, which did not get switched over to a new c-f. So for the SmR the c-f is SmR9, for Seoul it is S12.
In the initial “OB” card for the Marines in the Barricades CG should the second group be the 2/1 Marines rather than 3/1 (3/1 is referenced for 2 different groups)?
No. G and H Companies are correct as the is 3rd Bn. The black dot in the USMC RG Key, with 2/1 shown is because they take over from 3/1 after the first night (3/1 went into reserve thereafter), so when you are buying black dot elements later in the CG it is actually 2/1 then. Hence why both are shown in the key section.
