Master Chief Petty Officer Marcus-211, is a SPARTAN-II commando of the UNSC Naval Special Warfare Command. He became one of the most important heroes of the UNSC during the Human-Covenant War. He is one of the most decorated war veterans in the United Nations Space Command and has earned every known medal in the UNSC.

He is referred to universally by humans simply as the "Fleet Master", "Fleet Chief" for short.

Human-Covenant War
By 2531, Marcus had attained the rank of Petty Officer Second Class and helped the UNSC's assault. Marcus participated in countless battles of the war, one of the most notable being the Battle of New Mombasa, in which he saved his squad from a Hunter patrol five times the size of his squad and earned the command of an entire fleet. During the battle against the Covenant, Marcus' initial plan was to make a feint at flanks of the Covenant forces in order to draw them out and weaken their formation. Marcus planned to have the bulk of his forces attack from the rear and defeat them. However, when the Covenant let their forces split in two, leaving their center exposed, Marcus took advantage of the situation, breaking formation and eliminating the enemy, putting a quick end to the battle and avoiding further losses. However, in abandoning his position, Marcus left part of his own forces vulnerable and they suffered severe losses. The sole survivor of that stand, a Marine named Jack Edis, believed Marcus to be a cold-blood Grunt, and was determined to have his revenge.

Personality and traits
Marcus' demeanor can be described as bold and particularly audacious, and he seems to genuinely enjoy fighting. He is generally outspoken and somewhat pragmatic, and his vocabulary usually consists of wisecrack-ridden military banter. Even so, he is shown to be rational and has demonstrated the ability to put personal feelings aside and stay focused on the task at hand.
