ResearchDirectorChiefEngineerChiefMedicalOfficer: Take action

You schemed a scheme earlier, collaborating for a precise plan of attack. But only one of you has the physical strength and the substance of presence to make it happen. It takes fractions of a second to get a running start for a flying shoulder-check of a tackle that drives HeadOfSecurity into a nearby console.

ChiefEngineer may intend to replace Captain one day, but ambition doesn't mean a lack of loyalty. Captain would take a bullet for any of you. And so ChiefEngineer would take one for him. Each dance with the risk, in hopes that neither comes to pass.

ChiefEngineer: Drop it, bastard!
HeadOfSecurity: Hhhrk!
ResearchDirector: Get the gun--
HeadOfSecurity: Bitch!!
ResearchDirector: --away from him!
HeadOfSecurity: You'd put the whole--
ChiefEngineer: I said drop it!!
HeadOfSecurity: --frontier sector at risk, for--!
ChiefMedicalOfficer: Watch it! His grip--
ResearchDirector: The dominant hand!
ChiefMedicalOfficer: --is with the uninjured--
ChiefEngineer: Nnrrrhhh!
HeadOfSecurity: Get OFF me!
ChiefEngineer: Can't get it away from--!
ChiefMedicalOfficer: ChiefEngineer! Back off, get cover!
ResearchDirector: Captain!! HELP!!

Unfortunately, the plan fails to wrestle the gun out of HeadOfSecurity's iron fist. It keeps him disabled long enough for whatever comes next.

HeadOfSecurity Take advantage of ChiefEngineer's lack of depth perception
