I have some combat questions that are perplexing me:

How many rounds of can combat occur? After the initial round of combat of the Example Battle presented on pages 018 and 019 of the rule book, bcan the the USA player choose to continue attacking, using with the remaining Bomber and Partisan unit, or is the battle considered resolved after only 1 round of combat?

How many units from adjacent territories can assumed to be in combat position and attack a single adjacent territory?

1) Combat lasts only a single round. After this, the combat is over. If there are any defending units still remaining in the attacked territory, then the attacker cannot move into the territory to claim it after the combat phase.

2) Territories can be attacked from multiple adjacent territories, not just from a single adjacent territory. This means its possible to attack a city territory with more than 5 adjacent units (not including bombers). However, each friendly unit can attack only ONE territory in a turn so its NOT possible to use one unit to attack TWO adjacent territories.
