DECOMMISSION
As of March 16 2555, the SPARTAN IV program was officially decommissioned and production of SPARTAN IV supersoldiers was discontinued.
At the time, 800 SPARTAN IVs existed which was more than enough to fulfill the UNSCs need for special forces to be sent on high-risk deployment.BATTLE OF HAVEN
The Battle of Haven saw the biggest loss to the UNSCs infantry: the thousands-strong complement of marine and ODST soldiers were wiped out almost entirely with very few survivors. Almost all 300 SPARTAN IV supersoldiers were also rendered KIA with only 10 surviving.
CURRENT STATUS
As of September 2564, only 30 SPARTAN IVs remain. The SPARTANs are arranged into different Fireteams and continue to deploy on different assignments across GSU-controlled space. The nature of their missions are classified. The remaining Fireteams are as follows:
- Fireteam Aqua: Three active SPARTAN IVs
