Yeah that sounds right. I was thinking they wuld just roll in the first round but you could have them roll in each round until all the defenders units are gone. You could make them hit on whatever the IPC value is, or on a 1, whichever is greater. I would like to see islands and territories with no IPC value hit on a 1.
A question though-when do empty territory garrisons roll? I would think you record the movement and treat it like a battle, because otherwise if the first blitz failed you could try again (like sending planes over AAA in revised).
Im thinking it would work similar to naval mines in 1914. (That is you move, then check/roll dice)
Im also starting to think that we need a number system to determine what territories would roll at, as currently it is a bit high.
such as:
0-2IPC roll at 1
3-5IPC roll at 2
6IPC+ roll at 3
Critical areas (Russia, Germany, Italy, France) are rolling at a 2 or less.
While the major areas (UK, Japan, USA) are rolling at a 3 or less.
All the minor areas are only rolling at 1, and all territories get a roll.
You will never have a greater than 50% chance of killing a unit with a garrison alone.
