Oly Oly Oxen Free

Oly Oly Oxen Free is a six note, six beat tone used as an all clear code by the Spartan-II's. They learned it from Deja on Reach when they were younger and have been using it ever since. Spartans would either just whistle the tone or would whistle it and shout "Oly Oly Oxen Free" after. The proper counter-response was "Oly Oly Oxen Free, All out in the free, We're all free."

Psychology
Oly Oly Oxen Free was a secret amongst the Spartan IIs. They, and a select few outsiders knew it. Those outsiders were close to the Spartan II's "family"; such as Dr. Catherine Halsey, Cortana, and Sergeant Johnson. Thus, the signal was extremely important to each Spartan; they would rather die than give up the significance of the tone, which could potentially be used to betray or endanger their teammates. They learned this tune/code from their AI instructor, Deja, while they were training on Reach.

Uses
The term Oly Oly Oxen Free was used on numerous occasions throughout Halo. Some of the times it was used are as follows:


 * After the Spartan Team had beaten Tango Company and John-117 had checked to make sure their evacuation point was all clear.
 * After the Fall of Reach, Anton-044 used it as an S.O.S. signal over the E-Band.
 * In order to allow the Spartans to enter CASTLE Base, Kelly-087 used it to let Dr. Halsey know it was them.
 * During Operation: FIRST STRIKE, Linda-058 used it to let John know where she was so he could find her and pick her up.
 * At the end of Operation: FIRST STRIKE, Sergeant Johnson used it to let Blue team know that the Gettysburg was holding station behind a nearby moon.
 * When the rest of Blue Team, minus John-117 arrives on Onyx, Kelly whispers "Olly Olly Oxen Free" (probably a misprint as it is spelled with only one L), over the COM.
 * When Dr. Halsey takes Kelly-087 on the Beatrice with her.

Non-Canon Use
Marines use it on the Halo 3 level "The Ark" when firing on the first Covenant encampment, as well as in Crow's Nest, but only if the IWHBYD Skull is activated.
