- “Jeez, boss, maybe this wasn't such a good idea...”— Lieutenant Frye
- “If you've got a better idea, bring it up at the next staff meeting. Until then, shut the hell up and let me fly this thing.”— Carol Rawley
Carol did many missions involving hostile insertions and mounting rescues, and this made her stand out among the other pilots on the Autumn. Her copilot was Lieutenant Frye. She is technically an unseen character, as players can only see her aircraft and hear her voice until the release of Halo: Combat Evolved Anniversary where she is seen sitting in the cockpit. She is a member of the 23rd Naval Air Squadron, and she also appears to be the leader of the Pillar of Autumn's Pelican contingent. Her Radio Operator was Crew Chief Cullen.
Battle of Installation 04
- Main article: Battle of Installation 04
Not long after the UNSC Pillar of Autumn made a blind jump to the Threshold system, Covenant forces descended once again upon the ship. Foe Hammer escaped in the ensuing battle, and descended to the surface of Installation 04, where many United Nations Space Command forces had landed. While everyone else was escaping in lifeboats, she decided to lead the rest of the pilots and take their Pelicans down feeling that they would be useful. There, she helped John-117 and Cortana pick up scattered Marines and get them out of the battlefield and back to Alpha Base. She and Frye assisted John-117 and Cortana many times through the Battle of Installation 04, including inserting them to rescue Captain Keyes in a raid on the Truth and Reconciliation and sending reinforcements when needed, landing them and a squad of Marines on a beach to take the Silent Cartographer, ferrying them to the Control Room, and then taking them to the Flood Containment Facility.
Unlike most UNSC forces on Halo, Foe Hammer managed to survive the Flood outbreak by remaining airborne. However, she was shot down and killed by two Covenant Banshees when she attempted to pick up John-117 and escape Installation 04 minutes before the Autumn exploded and destroyed Halo. John-117 was deeply saddened by her death.
Foe Hammer was considered one of the best crewmen of the UNSC Pillar of Autumn. Fear was never expressed in her voice, and she was considered to have had the efficiency to get the job done. Foe Hammer put soldiers down on landing zones filled with hostile forces without hesitation, took heavy fire, ignored the odds and the consequences, and did not panic.
- In Halo: Combat Evolved, many pelicans and pelican wrecks have E419 written on them, meaning they are Echo 419, which, in many cases, would be impossible. In fact, there are only two pelican models in the game: they are Echo 419's and Victor 933's.
- The call sign "Foe Hammer" comes from the fourteenth level of Marathon Infinity. "Foe Hammer" is also a literal translation of the name of Gandalf's sword, Glamdring in J.R.R Tolkein's The Lord of the Rings legendarium, as well as the name of the dragon-slaying arrow in Stephen King's book The Eyes of the Dragon. Her callsign is commonly written as "Foehammer" by fans. It should be noted that Halo: The Flood and the Halo: Combat Evolved credits refer to her as "Foe Hammer"
- Foe Hammer is addressed by Cortana as a Lieutenant in the game, but is mentioned as a Captain in the book. However, it is possible that Cortana was addressing Lieutenant Frye, though this is unlikely, as Foe Hammer is the senior officer on board, and as such in charge of E419.
- It is possible to see Carol in the cockpit of her Pelican in Halo: Combat Evolved Anniversary. Her appearance is identical to the pilot of the Escape Pod which Master Chief rides from the Pillar of Autumn to reach Halo, and the model does not move her lips whenever she speaks.
