A whirring noise, a hatch opens and otherworldly soldiers exit the craft.
The German paratroops brace for the attack. The lieutenant does not want to fire the first shot, when you don't know the abilities of the enemy or even who they are, or if they are enemy, it's a good idea to wait. He has the troops, he has the tanks. He has a number of good advantages, maybe they will surrender?!!
The lieutenant is momentarily distracted by the sound of large vehicle motors behind him. More reinforcements perhaps?
