Evo-014's Summary
In the theater of conflict, Spartans, exemplified by individuals such as Master Chief, have occasionally ventured into battle as solitary warriors. However, the predominant approach for Spartans and other military personnel involves the formation of cohesive teams to achieve their mission objectives. These teams, often referred to as squads, typically consist of a limited number of members, generally fewer than ten individuals. Nevertheless, there are exceptions to this norm, exemplified by units like the 21st ODST Black Daggers, which comprise a full battalion numbering 800 soldiers.
Spartan Fireteams
Spartans, though fully capable of performing effectively as solitary operatives, are typically organized into fireteams, each comprising three to six members. These Spartan fireteams represent the epitome of precision and versatility in applying force, whether in combat or non-combat situations.Office of Naval Intelligence
ONI maintains a pervasive presence, with certain units operating openly within the public eye. However, the majority of ONI's activities remain shrouded in secrecy, exerting their influence throughout the galaxy without detection or awareness by the general populace.
