Null Spartans

Null Spartans were the only spartans that were not genetically modified. 
==Role==
Null Spartans were former ODSTs that were selected to take on the Spartan's places during halo 1-3. The reason why the UNSC used Null Spartans was to hold on the Spartan Legacy until more genetically modified Spartan programs could be put in place. During the timeline between halo combat evolved and halo 2 John 117 personally trained Null Spartans for one day before they were ready to go to battle. The other days they were trained by UNSC specialists who taught them advanced close combat, advanced tactical sense, and advanced ranged combat. These spartans learn how to use knives effectively to even the fight with stronger enemies. They also are heavy weapons specialists. They often put fear in grunts and demoralized the Coveant they would fight before they even fought because of the fact that they were Spartans. These spartans were better then ODSTs and useful in battle ;but their image was their special weapon.
