I think it is your squad that will get the capture. At least that is what I heard.
ok, that's fine, but why is there a field capture catagory in the players game stats? A year or two ago I'm sure I had a attack capture,and believe that's how I did it.
I know that if you're in a GV or goon and tower out or get killed while all your troops are out and running, and re-up before the map room is destroyed, you'll get the capture in whatever mode your in at the time....except for fighter and field guns.
I haven't found anything in the AH2 links or forums about this, but would sure like to.
