you spend squad points for battlefield position, or draw them randomly.
some examples could include:
Pitched battle - The dog fight takes place amongst a capitol ship battle, there are random turbo laser shots firing through the area. discard this card to perform an attack with 5 dice. the target doubles his defense dice for this attack.
HE missiles - discard this card to perform this attack against any enemy ship. Attack=4 if this attack hits, all ships within range 1 roll 2 attack dice and suffer any damage rolled and ships at range 2 roll 1 attack die and suffer any damage rolled.
just a few examples of off board support.
