I know alot of people don't know how the DS works so i hope this helps clear things up for you. http://img220.imageshack.us/img220/2667/92518020051130thumb0059kp.jpg edit: sorry it did not come out as large as i had hoped, to see it full sized go here: http://www.gamespot.com/pc/strategy/starwarsrts/screenindex.html pretty much what i wanted to show was that the DS has a count-down timer, as seen at the top of the pic, and on the control bar there is a leaver, when the DS is within range, you click (and maybe drag) the leaver down for it to fire. Some one asked before if it would be on the map with the ships and fighters, as that it is clearly shown with fighters and cap ships that answer is a yes.
