What is a halo spartan?

A Halo and a Spartan are two completely different things in the Halo universe.

A Spartan is a super-soldier created from a kidnapped child with cybernetic and biological enhancements by UNSC. The UNSC Civilian Doctor Catherine.H led the venture and also created the EPIC Mjolnir armor.

>>Spartans usually operate in squads such as blue team, the most recognised squad of spartans and certainly most elite.

>>There are two Spartans projects currently in existence that are conducted by the UNSC ONI Section 3 branch. The SPARTAN II project was led by Dr Catherine.H and was made public to battle the dwindling hopes of the Human-Covenant war. The SPARTAN II project derived from the ORION supersoldier project. The SPARTAN III project is an effort led by *********** and trained by Lt Ambrose with Mendez (who helped train the SPARTAN IIs) which never went public and were used to run suicidal high risk missions. While the SPARTAN IIs only consisted of around seventy soldiers, the SPARTAN III is known to have spawned three companies, each around three hundred spartans strong. Nearly every spartan is dead.

Halo is a ring in space round a star having the inner surface area many times the size of a planet available for habitation.

These rings however are Weapons of Mass Destruction on a galactic scale that are designed to destroy the "flood" - a race of parasitic aliens who have defeated all before them - by the slightly round about method of killing every sentiant being in the universe first so that the "flood" starve.

>> The halo arrays are radiological weapons of mass destruction* and were built to contain specimens of the flood as much as to wipe them out.
