in simultanious strategy mode(I can do it in tactical, you just move em up and hit the deploy button). I have 2 of them set to attack the planet, their strategy says "capture planet" but in combat they usually retreat and they haven't put any troops on the planet(the cargo is still full). Do I need to arm them or something or drop the cargo manualy(I'm haven't started sorting through all the strategy settings and what they do yet, been focusing on learning the tech tree, designs and managing the empire)?
