Steve does have plenty of Cruisers on the board, in his Home System and on Mecatol Rex.
But he decides it may be a better choice to not move with this Strategy Card. The Cruisers on Mecatol Rex need to stay there (and hope for re-enforcements soon). The Cruisers in the Home System are capable of moving 2 spaces as an ordinary action in his turn later this round.
Steve will wait to move these units.
Everyone has exercised the option to play the Secondary Ability from the Strategy Card Melissa chose. She flips the Strategy Card over (Inactive) but leaves it in her area.
The game turn resumes with the next player action in order as specified by the numbers of the Strategy Cards.
It's Nicholas' turn.
