My war story features suicide squads that are dropped from orbit on soft targets such as command elements or civilians. These soldiers are dropped without a withdrawl plan. They are expendable troops that just need to cause havok for as long as they can survive. If they do survive, advancing ground elements recover them for transportation back into orbit, or 'recycling'. I cannot make up my mind on an entry vehicle. I was thinking that they drop in an expendable, improvised reentry pod, but thats too much like the Warhammer space marines. Shuttles or transports are too expensive because they are expendable soldiers, and teleportation does not exist in my setting. I was hoping for some interesting ideas on this.
