Hi all, NO, that is just "Doubled" for every 'terrain' benefit of which is applicable. There are some "Games" where you could obtain multiple "effects" from this, as they'd have you tally UP those, and then 'subtract' ONE from this TOTAL amount for such, to then apply that multiplier.
I've just started playing TRC with my recently acquired Jedko Series II edition (PS rail counters seem to be Avalon Hill edition only) and I need to know if you can double the doubled defence if a unit qualifies for both. I have a Russian 5-3 infantry unit IN the mountains east of minor city LWOW behind the Dnestr river.
The Germans want to attack from the west but this might be a bit hard if they need to field a combat strength of 20 for a 1-1 attack. I can't see a reference to this situation in the rules. My guess is that you don't but I thought I'd better check. Oh yeah, so perhaps they ought NOT?
Thanks in advance

You can SAVE the entire 'image' of this, and then "crop" it down to where you have JUST a single series of those, or even create additional rows of them. Should YOU try that out at anytime, then please return and remark about HOW you liked it all!
