The Headhunters are a covert group of SPARTAN-III special operations squads. Only SPARTAN-IIIs who had survived two or more specially assigned training missions would be evaluated for induction into the Headhunters. Once an overall list of potential candidates was compiled, each soldier's personal files and mission reports were analyzed against a set series of parameters calculated by the top Office of Naval Intelligence specialists. Once selected, candidates were separated from their fellow SPARTANs and shipped to a special training facility on the far side of Onyx. After three months, the soldiers were broken into four two-person teams. These teams were chosen through a series of detailed evaluations and an intense interview process meant to devise the best possible pairings between members of the group. For the next two years, the Headhunters would go through seven months of supervised field exercises, followed by six months of real-world wartime insertions. These SPARTAN-IIIs would then perform missions far behind enemy lines and would likely die in combat. At the height of the program there was a maximum contingent of six squads - six teams with a total of seventeen soldiers rotating in to fill gaps when one or both members of a team were lost.
The Headhunters seem to wear more advanced armor than the standard-issue Semi-Powered Infiltration Armor used by most SPARTAN-IIIs. This armor includes motion trackers, energy shielding, VISR technology, and a prototype active camouflage module. The active camoflauge system can only be sustained for three to five minutes and diverts power from other systems while it recharges.
Two Headhunter teams participated in a failed mission on an unnamed Covenant-occupied moon, with notable members including Jonah and Roland.

Trivia
- The concept of the Headhunters is quite similar to that of the SPARTAN-II Program's Gray Team. Both groups are separated from their fellow SPARTANs and are sent far behind enemy lines for special covert operations. However, while the SPARTAN-IIs were aware of Gray Team, the Headhunters were a secret even to their peers.
