Series stars Grace Park and Katee Sackhoff do not appear in this episode. Tahmoh Penikett is also absent despite being credited.

Ironically, this marks the only script penned by Dawn Prestwich and Nicole Yorkin who were also writers and executive producers for The Education of Max Bickford, which starred Katee Sackhoff, who is absent from the episode. The duo left the writing staff simply for creative reasons, not getting into the show's science fiction/militaristic combination.

Tyrol: Doc, let's go. We're moving out. Doc, you hear me? We're moving out.
Baltar: No, I did hear you, Chief. I just don't respond to the title "Doc". A "dock" is a platform for loading and unloading material. My title is Doctor or Mr. Vice President, if you don't mind.
Tyrol: You are loading, are you not?

Tigh: (about Adama) Is he going to make it?
Dr. Cottle: How should I know? I'm not a psychic.

Tigh: Why aren't you in the brig?
Billy: Um... because no one put me in there.

Baltar: It's all so pointless. We kill them, and they kill us. So we kill more of them, so they kill more of us. What's the point anymore?
Number Six: You, your race invented murder. Invented killing for sport, greed, envy. It's Man's one true art form.
Baltar: You've done some killing of your own, I think.
Number Six: Yes, well, we're your children. You taught us well.

Baltar: He's crazy. I'm not trained for this kind of thing. I've never fired a gun in my life.
Seelix: I haven't fired one since Basic.
Baltar: (to Cally) You?
Cally: I just joined to pay for dental school.

Baltar: One of us will betray the others?
Number Six: Yes.
Baltar: During the attack?
Number Six: Yes.
Baltar: But if the attack fails?
Number Six: You'll die.
Baltar: Not me. I'm God's instrument.
Number Six: God turned His back on Kobol, turned His back on Man and the false gods he worshipped. What happens on Kobol is not His will.

Dr. Cottle: (after operating on Adama) He'll live.
Tigh: When will he wake up?
Dr. Cottle: Knowing him, when he damn well wants to, probably.

The title of this episode derives from the military term "frag" used to describe the murder of an unpopular superior officer in one's own unit. It originates from the Vietnam War when officers would use a fragmentation grenade to assassinate a leading officer.
