How? Pretty easy. Using Tactical, I ordered myself and 4 marines to the Transporter room. I then ordered the ship to Halt (from CC orders) and turned on the auto pilot, since I was going on the field trip and didn't want anyone left behind to go joy riding. While the crew was travelling, I opened TacOps and zoomed in on a friendly base. I clicked the "Transporter" button and then the "Setpos" to set the beam-in coordinates. Checking Perscan, I waited until we were all in the Transportor room. I then switched back to TacOps and clicked (I believe) the "Deploy" button. The game switched to a third person view of the surface and the 5 of us beamed in, complete with nifty graphical effect. I switched views around, playing, and then drew some of my weapons and used my guys for target pratice. When done, I opened TacOps back up using Alt-S and zoomed to myself. When I clicked on myself, a little menu popped up and I put a checkmark in the "Extract" option (again, I don't have the game or manual in front of me, I think that's the option). I clicked on "Extract" on the buttom Transporter menu, saw myself dissolve and ended up back on the ship, automatically on the way to MedBay. (I guess to check for infection or something after planetfall.) Pretty nifty, eh?
