Second Squad (Halo 2)

An ODST group led by Sergeant Pete Stacker, the Second Squad' was part of the UNSC Frigate UNSC In Amber Clad. During the First Battle of Earth, they fought in Old Mombasa. Upon In Amber Clads' arrival in Mombasa, it launched three Pelicans in an attempt to enter the Prophet of Regret's Assault Carrier. However, the three Pelicans were attacked by a Scarab and ended up as such


 * The first Pelican containing Master Chief Petty Officer John-117 and Sergeant Major Avery Johnson was shot down and landed in a nearby building. Everyone but the pilots survived.


 * The second Pelican avoided the hot Plasma turrets and rescued survivors.


 * The third Pelican containing Second Squad was hit and crash landed near a beach.

After an incident involving an Camouflaged Sangheili in the alleys of New Mombasa, the group met up with the Master Chief and a Warthog and continued to hold their newly claimed command post within Hotel Zanzibar.

It is unknown what happened to Second Squad. After Regret's carrier jumped, much of Mombasa was wiped off the map. Sergeant Stacker survived so it's likely that the Squad got back to In Amber Clad on another Pelican.
