Survivors of Installation 04

Survivors of Installation 04
After the destruction of Installation 04, Spartan 117 and Cortana, who were responsible for the ring's destruction, fled the installation of a Longsword. Shortly afterwards, they reunited with 5 other survivors on a Pelican. The survivors of the Battle of Installation were as follows;

On the Longsword

 * Master Chief Petty Officer John 117
 * UNSC AI Cortana

On the Pelican

 * Sergeant Major Avery J. Johnson
 * Corporal Locklear
 * Lieutenant Elias Haverson
 * Warrant Officer Sheila Polaski

Unknown
The following two Marines have been seen after participating in the Battle of Installation 04, but it is unknown how they made it off Halo before the explosion. Note that there may have been other survivors.
 * Sergeant Pete Stacker
 * Private Chips Dubbo

It should also be noted that Linda 058 survived the destruction of Halo, even though she was in cryosleep the entire time.

The survivors of the Human-Covenant War
However, not all these Marines survived the remaining war. Corporal Lockear was killed by a Slipspace crystal. It is theorized that this may have been suicide over his grief at the loss of Shelia Polaski, killed by a Slipspace bubble along with two other Spartans. Lieutenant Haverson along with Admiral Whitcomb took a wounded Flagship and waged a one-ship attack on the Covenant fleet gathered around Unyielding Hierophant, destroying the Unyielding Hierophant which destroyed about 500 other ships. Johnson was killed during the battle of the Ark, and Master Chief and Cortana were MIA after that same battle.

Pete Stacker and Chips Dubbo participated in the 21 Gun salute at the end of the war.
