UNSC Two for Flinching
From Halopedia, the Halo wiki
The UNSC Two for Flinching was a UNSC Corvette.
The Two for Flinching was the corvette that took Staff Sergeant Avery Johnson and Petty Officer First Class Healy from Earth to Harvest.
The fast attack Corvette is known for being the UNSC's smallest capital warship and carries no fighters because the only thing that can fit inside a Fast-Attack Corvette's hangar bay is a SKT-13 shuttlecraft which is a reusable version of the UNSC's Bumblebee life boats.
Trivia
The Ships name is a play on a saying in hockey when a player gets a minor penalty, "Two for [Penalty such as slashing or cross checking]". It may suggest that the enemy will flinch and suffer a penalty in battle.
