Star Wars: Battaglia di Hoth

You draw a new Command Card as the last step of your turn: after resolving all attacks, hits and retreats you discard the card you played and draw one (reshuffle discard into deck if empty). (Rulebook p.4, p.7).

Yes — a unit on a hex cut by a red dotted line may be ordered from either section when you play a Section card. (Rulebook p.4).

It depends on the unit and how far it moved: for example, infantry can move 1 hex and still attack (moving 2 prevents attacking), and a snowspeeder can move up to 3 hexes and still attack; check unit stats for each type. (Rulebook p.5).

Each retreat icon forces the targeted unit to retreat one hex toward its baseline (player chooses legal hex), terrain generally doesn’t stop retreat except impassable hexes, and if a unit cannot complete a required retreat it suffers one casualty for each uncompleted retreat move. (Rulebook p.7).

You must have an unblocked line drawn between hex centers—units or terrain that intercept that line block fire—and terrain protections/penalties reduce the number of attack dice rolled; special edge and ridge cases are detailed in the rules. (Rulebook p.6, p.12).

Infantry icons score hits vs. infantry, vehicle icons score hits vs. vehicles, blast icons score a hit on any unit type, and the cross is a miss; hits remove miniatures and excess hits beyond a unit’s miniatures have no effect. (Rulebook p.7, p.6).
