In the rules it says you can trade three 1.0 MOD for one 3.0 MOD and that the 3.0 MOD is worth 3 armies. In the rules of Invading territories you roll 1, 2 or 3 dice, and you must have atleast one more unit than the number of dice you roll.
If I have one 1.0 MOD and one 3.0 MOD and attacks, is that 1 or 3 dice rolls? Or are armies and units different in the context?
