Some editing at the beginning results in some confusion. When the invaders enter the Missile Room, the crewmen jump to the attack and are restrained by the officers. No shots are fired, no one is clubbed, knifed, or otherwise struck. After the opening credits, the scene returns to the Missile Room. If you look closely, you can see a body on the floor behind the men. A short time later, Chip Morton refers to "Henderson and Purcelli". Purcelli has been "taken away"--presumably killed; Morton is not certain about Henderson. The audience is left wondering.
