I read in a review that close assault is done in part by rolling one die: "Close assault is odds based, with particular odds giving a kill number, which is resulved with the roll of a single die." The rules in 15.7 says dice roll and the example says roll 2 dice. I am confused if the review is talking about the same thing. The way that I understood the rules is that 2 dice are used.
Also, can 2 units attack the same hex and all the units in it if the attacking hexes are not adjacent to each other? See scenario Messenger Ambush as an example. Can the 2 hexes containing the US units fire at the German squad in I4 if that unit moves to H4 during the opportunity fire?
One last question: is defensive fire the same as opportunity fire? 5.33 and 5.34 and 13.8 make this a little confusing. 13.8 says that opportunity fire is a form of defensive fire. Is defensive fire done if shot at by the opposing player not necessarily just during the opposing players movement phase?
The close assault rool, is a single roll of a pair of dice.
"Only infantry units from the same hex may conduct a close assault together; they may not combine with infantry units from separate hexes"
"Any number of close assaults may be conducted against the same hex during the same turn, but each close assault must be resolved separately"
... so two hexs make may two seperate attacks against the same target hex.
Opportunity and defensive fire are seperate. With opportunity fire you shoot during your opponents move phase. Defensive fire is seperate phase where you have the chance to shoot.
