In the world of the 33rd Century, well over 700 years following the events of the Halo games, the UNSC military is still strong with the most versatile branch of defense, the UNSC Marine Corps.
Still tied to the traditions of the ancient USMC, the Marines of this era employ more technology and education than Marines of previous eras, making them not only one of the best equipped fighting forces in Known Space, but the most educated as well!
Marines can come from any walk of life and any world, ranging from the sprawling cities of Earth to the tiniest farming hamlets on Durandel 14,000 lightyears from Sol. This particular Marine is Master Corporal Avermann of the New Israeli State of Earth.
Some Marines carry personal shield generators which will save them from small arms fire which can be a very important asset in many combat situations, and can operate in any setting, including but certainly not limited to the near perfect vacuum of space.
Recently in late 3234, the aliens from an alternate version of Earth, the Mobians have joined the ranks of the UNSC Alliance in order to protect Human Space, and any other race that requires one of the best doses of Grade-A motivation this side of the Tagrin Rings!
