ODST- Orbital Drop Shock Troopers
The ODST's or Orbital Drop Shock Troopers are the special forces branch of the UNSC Marines. They participate in the all of the most dangerous and risky missions humans partake in. The preferred method of insertion is from an orbiting warship, they are dropped in SOEIV atmospheric re-entry pods. Though they were not given resources equal to that of the Spartans, the ODST's were the second greatest thing humanity had. That also led to a rivalry with the Spartans as well.
