The basic concept of the SPARTAN program has been around since the late 22nd century when the first bio-engineering protocols were developed for interplanetary war. Since the establishment of these protocols, humans have been using performance enhancing equipment and augmentations to make them stronger and faster than previously thought possible. These super soldiers have been deployed numerous times throughout human conflict, leading up to and during the Human-Covenant war
. The SPARTAN program first arose as a brilliant plan to enhance normal human soldiers into powerfully augmented special operations commandos. Initially, the three separate programs were humanity's various attempts to create the perfect soldiers, in order to patrol the colonies, protect civilian and government populations, crush uprisings in their infancy and ensure others didn't rise up as a result.
The SPARTAN soldiers of the UNSC are named after the ancient Spartans of Greece, specifically during the famous Battle of Thermopylae
. Catherine Halsey
had three reasons to choose SPARTAN, rather than many other suggested code names. She believed the story of Thermopylae continued to be well-known and cherished throughout the 26th century. Coincidentally, the project was originally funded for 300 applicants. The Spartans' fierce reputation resulted from their legendary training, which began at the age of 6. Dr. Halsey
planned to recreate a training system similar to the Spartans' in order to create the ultimate warrior. Spartan culture was based primarily on warfare, destroying newborns unable to meet strength and fitness requirements. Although considered barbaric during the modern era, Dr. Halsey
arranged similar demands.
