Duke Grecko was a Confederation Marine who served during the Terran-Kilrathi War.
Grecko had been friends with Geoffrey Tolwyn since their days together at the academy. He is only 5 ft tall. People called him Big Duke because of his "pugnacious attitude", always looking for a fight. His combat callsign later became "Big Duke One."
As a marine commander, Grecko was in charge of the entire landing assault on Vukar Tag on 2667.160. He went in with the commando battalion to lead the assault himself from the ground. Grecko was known even to Crown Prince Thrakhath nar Kiranka as the best marine division commander. In the holo-recording sent from Vukar Tag, Grecko is seen relieving himself against the palace walls. Grecko lost an arm in the Kilrathi bombardment of Vukar Tag, but he had a new one generated.
Two years later during the False Armistice, Duke was a Marine General on the Joint Chiefs of Staff, and sole survivor of the explosion that killed the Joint Chiefs. He had walked out of the meeting with the ambassador, and had been at the far end of the corridor when the bomb went off. The explosion ripped off Grecko's artificial left arm that replaced the one he lost at Vukar Tag. The limb absorbed a blow from a falling pillar that would otherwise have killed him.
By the time the Confederation discovered the secret Kilrathi fleet, Grecko was the head of the Joint Chiefs. Grecko intended to board the incoming Kilrathi ships with Marine landing crafts.
When Grecko's unit boarded a Kilrathi carrier, they tried to get at far into the ship as possible to detonate an anti-matter mine. Grecko's good arm was shattered by a grenade aboard the Kilrathi flagship. Grecko volunteered to stay with the mine, giving the team time to get out, and was killed when the mine was detonated by Jenny McCrae, a friend of Duke's daughter.
He was survived by his daughter, Jenny Grecko, also a Confederation Marine present during the Battle of Earth.
