Spawn as any class you like, at the hangar CP. Jump on top of a parked Snowspeeder and wait until it takes off. Soon, you will begin to slowly go through the hull of the craft. As you fall through the snowspeeder towards the ground, the snowspeeder you were just on will explode in midair, killing your AI teammates. The casualties you caused will not count against you, so you won't be called a traitor. Those pilots just won't know what hit them.
