Hi Chris,
The Questions and Answers are:
Q: The dice roll under 45.2 to determine what kind of support is known to both players, and only the number of fire missions is secret, correct?
A: Correct. This is contradiction to 45B of the Squad Leader Conventions, but for this tournament let's stay with rule 45.2 as the default position.
Q: Is the dice roll under 45.2 done for both German modules at the start of the game? Or does the German have to wait until the second radio is on the board before he rolls for the second module of artillery support?
A: Yes, both modules are rolled for at the start of the game.
These are the default positions for both of these questions. If both players agree to keep the caliber of the module secret, the number of missions to be fired and/or if the second radio is rolled for when it enters the game, these are all acceptable. If both players do not agree to these changes the default position outlined above will govern.
