Command branch characters tend to fill roles in the administration and logistics in my games. Remember that the conn officer is usually command branch - in my game conn is a command function and under the command branch and not ops.
The best way to handle command branch characters is to rotate them around each branch to give them a general feel of what each branch does.Command characters are flexible and should move around to learn every aspect of ship handling and command to make them better executive officers and captains later.
Arise, arise, Riders of Theoden!
Fell deed awake: fire and slaughter!
Spear shall be shaken, shields be splintered,
a sword-day, a red-day, ere the sun rises!
Ride now, ride now! Ride to Gondor!
