OFFICE OF NAVAL INTELLIGENCE
Table of Organization and Equipment — TOE, T/O, T/E
Table of Organization and Equipment is the specified organization, staffing, and equipment of units. Also used in acronyms as 'T/O' and 'T/E'. It also provides information on the mission and capabilities of a unit as well as the unit's current status.
TOE is granularly the roster for each unit, however the principal of the concept is all throughout ONI. TOE was adopted into ONI after observing large gaming communities and playing Halo Wars in its real time strategy game around UNSC units and deployment.
All forces under HIGHCOM's authority are loosely modeled on the organization of the 21st century United States military. The force numbers given in the descriptions below are ideals, rarely matched exactly in the field. At the higher levels, these numbers include a significant amount of support personnel such as logistics and administration. Due to the UNSC Air Force never successfully being executed all Air Force compositions are unlisted, the entirety of this channel has also been condensed for Discord visit the website for full details on all compositions.
A fireteam is the smallest unit of armed force organization. It contains a total of three soldiers plus a fireteam leader, usually a E4 corporal, petty or sometimes a E3 lance corporal in the Marine Corps.
While fireteams are specialized to operate in 'firefights' other teams can have different purpose as jump teams, ferret teams and SPARTAN teams.
A squad contains three fireteams led by a sergeant for a total of thirteen members. Squads are ubiquitous with the UNSC Marine Corps. As forewarned before the numbers of total members ranges with leadership and unit.
A work crew or work party is the Naval equivalent to Squads, often colloquially called a squad. Work crew is led Petty Officer Third Class (PO3) with a specialized goal in multiplayer matchmaking game modes or campaign story mode.
A platoon normally contains three squads (39 personnel); plus the platoon leader, a Second or First Lieutenant; the Platoon Sergeant (the second-in-command), usually a Sergeant or Staff Sergeant; and a medic, for a total of forty-two men.
A compartment is the Naval equivalent to Platoons normally containing 3 work crews. Compartments are led by a work division supervisors of the rank Petty Officer Second Class (PO1) along with compartment supervisors of the rank Petty Officer Second Class (PO2) who advise work party leads. Compartments are always in reference to Navy components with the optional naming convention of Navigational Compartment, Engineering Compartment, Security Compartment, Communications Compartment and Combat compartment. Compartments are based completely off Watchkeeping or watchstanding: the assignment of sailors to specific roles on a ship to operate it continuously.
Deck - Detachment
A deck is the Naval equivalent to Companies however slightly larger compromising of anywhere from entire company to a battalion. Decks are led by a Deck supervisor, a Lieutenant Junior Grade or Lieutenant along with Compartment supervisors who advise work party leads. Decks are always in reference to Navy components with the optional naming convention of Marine Deck, ODST Deck/SOEIV Bay and Spartan Deck to specify branch and Detachment.
Each Deck is complemented with a detachment of another operational unit, promoting cohesion and accuracy. A detachment is typically a Platoon or Company of another branch or unit. Detachments can also be specialized sub-units shared between multiple units.
A company contains four platoons plus a group of personnel assigned as "Company Headquarters Section" (164 personnel). It is commanded by a captain with a company first sergeant. The twelve companies in a brigade or regiment are named phonetically "A" (Alpha) through "M" (Mike) with the exclusion of "J" (Juliet). First Battalion consists of companies A through D, Second Battalion is companies E through H, and so forth.
A typical infantry company would have three infantry platoons and one heavy weapons platoon, but these numbers are flexible depending on the unit type and mission.
A ships (depending on the size and class) are comprised of two to eight decks in addition to the "Command Bridge/Deck" equivalent to the company headquarters section of an infantry assignment. Ships are commanded by the size however authority always begins at Lieutenant with an command staff consisting of a operations officer, navigational officer and communications officer again dependant on the size and class of the ship.
A battalion contains four companies plus a group of command and staff personnel assigned as Headquarters Company (eight hundred personnel). It is commanded by a lieutenant colonel with a battalion sergeant major; this would be a sergeant major in the Marine Corps or a command sergeant major in the Army.
A Marine Corps regiment contains three battalions, plus a group of personnel assigned as Headquarters Company (3,000 personnel) commanded by a colonel with a sergeant major as senior non-commissioned officer. Clan functions are stressed at this size and following lore which is heavily influenced by 21st century military (present day operations) Regimental Combat Teams (RCT) are used as a provisional major infantry unit formations from typical Regiment organization.
A battle group, sometimes rendered as battlegroup, is an organization of ships that is generally smaller than a fleet. Battlegroups are subdivisions of a UNSC fleet, flexible fighting formations that can formed on an as-needed basis in several different tactical formations, which themselves can be "plugged together" into ad-hoc task forces. Battle groups are usually created on a temporary basis, with a specific mission or to accomplish a specific task. Battle groups can range in size from as little as three ships to larger carrier groups with smaller "tactical" carriers at their core. These battle groups are referred to as carrier groups.
ONI also employs specialized operations and actions group for specific special activities. Ranging from politically destabilizing to materials exploitation and roleplaying elements. These groups are to be considered the same as Battlegroups regardless of their navy-less functions.
A task force are a fleet composition element employed by the UNSC Navy. Task forces are typically interchangeable with battle groups, being ad-hoc fighting forces formed from Naval tactical formations. Task forces are created on the basis of necessity per campaign or military operation in ONI. While above battlegroups task forces can be created under battle groups as sub-units.
A fleet is a large, permanent organization of ships. Fleets are usually relatively large and manned by thousands of individuals on what is normally dozens or hundreds of ships. UNSC fleets are divided into Expeditionary and Defensive fleets. They are typically assigned to Sectors. Sector fleets are usually commanded by a Vice Admiral.
Defensive fleets are typically named after the star system they are based in. Expeditionary fleets are numbered fleets designed for offensive operations into deep space. UNSC fleets are comprised of numerous battle groups, smaller tactical formations of ships. Naval fleets rarely patrol together, and it is fairly common for single ships to patrol regions of space alone.
A corps. is divided in two terms an operational formation, an administrative formation by definition. Operational formations are the Signal corps and the Prowler Corps, which consists of two or more divisions. Administrative corps – that is a specialized branch of a military service including the Engineering Corps, Logistical Corps, Medical Corps, Press Corps and the Judge Advocate General's Corps.
It is important to understand that the UNSC Marine Corps. is a uniformed military branch and not a corps division. The naming convention is not to be confused with Corps.
A division contains four regiments plus a group of personnel assigned as Headquarters Battalion (14,000 personnel) commanded by a major general. The extra personnel in the force number given are support units, including medical, combat engineering, maintenance, and military police.
ONI is considered a division. The military intelligence division to the UNSC (not no specific entity) While encompassing multiple naming conventions of other divisions under its composition.
