Randall Aiken

Randall is a SPARTAN-II super soldier who may have been Killed In Action in 2532. However, Dr. Catherine Halsey considers him one of the few Spartans truly MIA. Little is known of him, except that he was not as sociable as Kurt-051.

A possible Halo 3: ODST easter egg has been interpreted as corresponding to Randall. The license plate reads "KMA 037R" which presumably stands for "Missing in Action, Randall-037". (Note that the "K" is commonplace in the plates and does not represent the word "killed")
