In the spirit of Star Trek, here are the members of the Hazard Team who can die (usually due to your incompetence):

• Tom Odell. Being sighted by too many Klingons on the Find the Isodesium Mission (the Scavenger Base) will result in his death when Munro finds him.
• Ken Lathrop. Dies when the Borg attack trying to seize the isodesium.
• Lt. Foster. Dies if Munro fails to deactivate the "assimilator" device in the Borg Cube. Detour around the forcefields to get to Foster's cell to save him.
• Jeff Nelson. Can die during the fight in the Borg Cube.
• Mitch Csatlos. Can die on the Dreadnaught Vessel if he takes too much damage (or falls off an elevator).
• Rick Beissman. Dies on the Dreadnaught Gunship.
