Editing Oly Oly Oxen Free

'''Oly Oly Oxen Free''' is a six-note tone used as an all clear code by the [[Spartans|SPARTAN IIs]]. They had learned it from [[Deja]] when they were younger, and had used it ever since they first trained on [[Reach]].

==Psychology==

Oly Oly Oxen Free was very secret to the [[Spartans]]- no one but them and a select few outsiders knew it. These outsiders were close to the Spartan family, such as [[Dr. Catherine Halsey]], [[Cortana]], and [[Sergeant Johnson]]. The signal was thus very important to each Spartan, who would rather die than give up the significance of the tone, which could betray or endager their teammates.
 
==Uses==

Oly Oly Oxen Free was used on numerous occasions throughout [[Halo: The Fall of Reach]] and [[Halo: First Strike]]. Some of the times it was used are:

*After the Spartan Team had beaten [[Tango Company]], and [[Master Chief|John-117]] had checked to make sure their evacuation point was all clear.
*After [[The Battle of Reach]], [[Spartan-044|Anton-044]] used it as an S.O.S. signal over the [[COM|E-Band]].
*for the Spartans to enter [[CASTLE Base]], [[Kelly-087]] used it to let [[Dr. Halsey]] know it was them.
*During [[Operation: FIRST STRIKE]], [[Spartan-058|Linda-058]] used it to let John know where she was so he could pick her up.
*At the end of [[Operation: FIRST STRIKE], [[Sergeant Johnson]] used it to let Blue team know where the Gettysburg was holding station behind a nearby asteroid.
