Lieutenant Dante Kirtley was a UNSC Navy officer who ran the communications station with Lieutenant Burt on the UNSC Midsummer Night in 2534. He was responsible for relaying messages throughout the ship. Kirtley believed that the Office of Naval Intelligence tortured their prisoners, which greatly offended Major Akio Watanabe.
When Lieutenant Badia Campbell mortally wounded Commander Dmitri Zheng and shot him and Li to boot, Kirtley recovered from his shoulder wound and tried to give Zheng medical attention. However, the Commander refused, instead going to lock the codes to the Shiva-class Nuclear Missiles onboard and broadcasting the ship's surrender to The Rubble. On the orders of Maria Esquival, the Insurrectionists captured Kirtley and the rest of the crew, but the SPARTAN-IIs of Gray Team soon freed them and they boarded the freighter Mighty Sparrow, and onboard Kirtley continued to serve as communications officer before they moved back to the Midsummer Night. He was the first to notice that the Jackals were moving out of the Rubble.
