Hi, two questions about ships.
1.- During the invasion turn, can german artillery fire to the ships that the allied played placed in the thirth phase.
No; not until the regular game turns.
2.- If you place more than one ships in hex an you recive fire from germam artillery. Can you apply the stacking die roll modifier to the artillery fire?
No; the ship counters are abstracted and the stacking multipliers don't apply.
