the Twilight Empire launches a surprise invasion into the Etra Empire striking with all their available might at the weakest points, pushing through and then surrounding the stronger defensive points... the sheer size of the army overwhelms local defenders who fight bravely holding off the attacking army for as long as possible hoping to outstretch the enemy... the get get close... many notice that somehow they are getting blown up when there's nothing there... a ghost tank maybe? no can't be... darn stealth tanks...
