Drill Sergeant Nasty: In "Clone Cadets", the clone cadets of Domino Squad are under the charge of Master Chief Petty Officer Bric, a Siniteen bounty hunter with an oversized brain. He does not seem to actually have the clones' best interests at heart, but his tough style seems to work and get this particular group of clones motivated to pass their exams.
Dwindling Party: Domino Squad serves the role as this. In "Rookies", Droidbait is among the first to be killed by the invading Separatist droids, Cutup gets eaten alive by a Rishi eel, and Hevy is forced to pull a Heroic Sacrifice when the bomb's remote has a malfunction. When Echo and Fives return to Kamino in "ARC Troopers", 99 (who is an "honorary" member of the Domino Squad) gets killed just before they're made ARC troopers. Echo and Fives are the only members of Domino Squad to survive the events of this story arc.
No One Gets Left Behind: In "Clone Cadets", Domino Squad receive an automatic failure on their final test when they abandoned Droidbait after he was more seriously wounded than intended during the simulation. They are told explicitly that they broke the number one rule.
Spoiler Title: The episodes in this story arc are titled after the ranks that the clones in the Domino Squad have.
