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.[1]
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.
