Exactly. The mission decides the tool/unit that gets used.
For this exercise the location and type of the mission (and the story conflict and plot
) will determine the nature of the unit and how well it fits the mission.
For story purposes, tough, it might even be a good idea for the unit to be a *bad* fit.
