Si Wheeler

Si Wheeler, callsign Intrepid One, is a SPARTAN-IV supersoldier who served as team leader of Fireteam Intrepid in the United Nations Space Command.

Reach
In October 2559, Fireteam Intrepid, presumably including Si Wheeler, was deployed alongside Fireteam Taurus, assigned to aid Commander Sarah Palmer in securing nuclear weapons in possession of the Viery Militia toward the end of the Battle of New Mohács.

Installation 07
On December 12, 2559, Fireteam Intrepid was onboard when it was ambushed by Banished forces upon arrival at Installation 07. As the Infinity fell to the Banished assault, Captain Thomas Lasky was evacuated from the ship, and Spartan Hudson Griffin ordered all Spartans to evacuate. Fireteam Intrepid left the ship on drop pods, and landed in a sector of the ring occupied by the Banished. The Spartans entered battle upon landfall.

On the next day, Fireteam Intrepid was in a skirmish against the Banished when an explosion on the ring caused a fracture on its surface. Amidst the chaos, Tomas Horvath was separated from the rest of Intrepid. While the status of Si Wheeler remains uncertain, Horvath remained active as of May 2560.

Personality and traits
According to Tomas Horvath, Wheeler might just have the worst potty mouth of the entire Spartan branch, despite Wheeler himself had repeatedly sworn that he did not curse as much as the rest of the Fireteam Intrepid.
