Commanders are usually assigned at the very beginning of the round by pre-joins and proper preferences being set up. This means, you’ll likely never get this role until you’re chosen for it out of the hat. Well looks like your the leader of the marines, your main job will be to look like a real commander lead the marines to victory at all costs, you don't want to look bad, now do you? Make sure you brief your fellow marines at the start of the mission. How you do so is entirely up to you Commanders are the top dogs on the mission. You’re to follow all their orders and make sure that what he says is what happens. Playing as this role follows the same rule as most station-bound roles, which includes leaving the Sulaco to board the Nostromo. Don’t do it. Commanders should always remember that an act of mutiny is a legitimate RP scenario, but can be banned for if abused. This means, don’t make stupid decisions and don’t do stupid things. You’re a Commander, not a five year old with military command education. So now go, make the marines victorious my commander! Good luck Commander.
