Dmitri Zheng

Dmitri Zheng was a Commander in the UNSC Navy. In 2534, he had command of a UNSC Light Frigate, Midsummer Night. Cmdr. Zheng had lost his previous frigate by ramming a Covenant destroyer. Many people thought that he had done this in anger and out of revenge, but Zheng later told Lt. Jacob Keyes that he had run out of tactical options. Zheng only avoided a court martial because the destroyer was subsequently taken out by another ship's MAC.

Zheng died at the Battle of the Rubble after the ship's reactor went critical. He surrendered command of the Midsummer Night to Keyes.
