7th Orbital Drop Shock Trooper Division

The 3rd Orbital Drop Shock Trooper Battalion was one of many units of UNSC Orbital Drop Shock Troopers in operation in 2552. Members of this battalion were stationed aboard the UNSC In Amber Clad during The First Battle of Earth. It is they who traveled to Installation 05 and "Helljumped" to the surface along with the Master Chief. They are the only ODST's seen in the Halo 2 video game.

NOTE: The battalion number comes from a patch that was designed for Halo 2 and intended to be used on crew members of the In Amber Clad''. The patch was shown along with the In Amber Clad patch in the book The Art of Halo. It is not clear whether or not this patch was ever actually seen on the shoulders of any characters, as the In Amber Clad logo was.''
