Mark Jamison Sheppard is an American soldier and the brigadier general represented as the first supreme leader of the United Nations Global Defense Initiative and exclusively appeared in the first installment of Tiberium Universe, originally known as Command & Conquer: Tiberian Dawn.

Also, he has a son named Logan Sheppard, who is assigned to his organization as a special force unit.

During the First Tiberium War, in every Tiberian-based operations in Europe, Sheppard was forced to become the political leader of GDI instead of a pure military capacity. For example, the major outbreak was the Bialystok scandal, where the war crime was erroneously accused by GDI for slaughtering and reported by the newscaster for the Brotherhood of Nod. Sheppard manages not only to blunt offensive media of Nod but to secure the latest economical funding from the united Nations and direct a vigorous opposition against his notable enemies, especially driving out the return to the temple of Kane in Bosnian capital of Sarajevo.
