All questions are good!
i'm studying rules and some time i have doubts about my understanding !!
so i allows me to ask some questions!!
sorry if they may seem basic or stupid !!
in the living rules you said that :
"In all cases, if any of your units have 1 or more printed Factors of the type for that Round, then the minimum number of Factors you can have after all modifications is 1."
"If none of your units have 1 or more Factors after all modifications, then your side does not roll."
Is it mean the units for the second ligne did not have at least 1 or more printed factors ? or you speak about units with no land primary factor ?
I'm sorry this isn't clear. I'll try to say it differently.
(1) If any of your units have 1 or more printed Factors for the type of Round you are doing, then your minimum Factors after all modifications is 1 (even if the modifications due to good defensive Factors reduced you below 1).
Example: In a Land Round, I Ground Attack with a 1 Land Factor GAR against a unit that is -2 defensive Land Factors. I still roll on the '1' column (even though my final modified Land Factors are -1).
(2) If none of your units have 1 or more printed Factors, but you gain
some modifications (from bad enemy defensive Factors) and end up with some positive Factors as a result, then you get to roll with those Factors.
Example: In a Land Round, the other side is attacking my GAR that has 0 Land Factors. Two of the attacking land units both have a +1 defensive Land Factor that adds to my total Land Factors. I end up with 2 Land Factors and roll on the '2' column.
(3) If none of your units have 1 or more printed Factors and you don't gain any Factors from modifications, then you don't roll.
Example: use example #2 but suppose none of the attacking land units have any positive defensive Land Factors. Then my GAR still has 0 Land Factors after all modifications, and thus does not roll.
Hope this helps,
