One of the things I've noticed very little on in the books is any details on getting the characters to and from their mission. If by ship for example, what are the Deathwatch's fleet assets, and what happens to it afterwards? Having a ship in orbit seems like a heck of an asset to have. Then there's getting to the site itself. How do you get the team in and out without giving them a huge asset like a Thunderhawk or Stormraven that they can exploit througout the mission? If you use drop pods, how are the characters extracted at the end of the mission?
I'm preparing to run my first DW game, and I know my players are going to try and squeeze every asset they can out of me .
