Sheila-065

Were you looking for Warrant Officer Shiela Polaski, or Sheila, the character from the machinima Red vs Blue?

Sheila was a SPARTAN-II super soldier. Next to nothing is known of Sheila as she was only mentioned by Dr. Catherine Halsey in the Halo novel, Ghosts of Onyx. Dr. Halsey witnessed her death during the Battle of Miridem in 2544. .

A possible Halo 3: ODST easter egg has been interpreted as corresponding to Sheila. The license plate reads "KBM 101S" which presumably stands for "Battle of Miridem, 101 Sheila". (Note that the "K" is commonplace in the plates and does not represent the word "killed")

Trivia

 * The sentient tank from the popular machinima series Red vs Blue has the same name.
