Spartan

Spartans are a genetically engineered type of human from the Halo universe.

Physiology
Spartans stand at an average of 7 feet tall (fully armoured), and have a reinforced endoskeleton. Their training and physical conditioning along with the chemical and genetic enhancements give them super-human speed, strength and endurance. They are able to punch through solid concrete without doing damage to themselves.

History
The first Spartan program, called Project Orion, was the UNSC's attempt at mass producing super-soldiers in order to control a growing populace.

Although it was considerd a failure by many (the Spartans falling far short of expectations), the idea stayed.

In 2524AD the project relaunched as the war against the Covenant erupted. Out of 200 five year olds chosen, only 75 became Spartans as most either died or "washed out", crippled as result of their training.

After more than 20 years of warfare most Spartans died at the fall of Reach (2552Ad). All but two were killed- John 117 Masterchief and Jun A226 Noble 3.

(although there could be five if the three aboard Spirit Of Fire are included, although they are Project Orion not Spartan 2's. These are Douglas 042, Alice 130 and Jerome 092)
