Organizational Military Units (Halo Movies)

Organizational military units in the Halo films.

Fireteam
The smallest UNSC infantry unit and they generally consist of four troops, although they can include up to seven soldiers and are grouped into squads. A fireteam is capable of autonomous operations as part of a larger unit. Successful fireteam employment relies on quality small unit training for troops, experience of fireteam members operating together, sufficient communications infrastructure and a quality non-commissioned officer to provide tactical leadership for the team.

Member Roles:
 * Fireteam Leader: First in command, provides tactical leadership and a fireteam can be led by a Sergeant though a Lance Corporal is also suitable to take command. They are often armed with an assault rifle or a battle rifle.
 * Scout/Designated Marksman: Looks out for any signs of hostile enemy forces. They would normally carry a scoped weapon such as marksman rifles and sniper rifles.
 * Rifleman: The most common role in a fireteam and several riflemen may be incorporated into a fireteam but in some situation, only one is needed. They often carry assault rifles and provides suppressive fire for the team. They are considered the backbone of operations for the UNSC infantry as a whole.
 * Specialist: For added firepower against a large number of enemies or vehicles, this soldier or marine may carry a heavy weapon such as a rocket launcher or a light machine gun. In close-quarters battle or urban combat situations, a specialist may choose to wield a shotgun as opposed to a carbine or SMG.

File
A file is the smallest infantry unit within the Covenant and usually consists of four to five Grunts or Jackals and is often led by a Brute Minor, Elite Minor or a Grunt Major.

Lance
A lance is the second smallest infantry unit within the Covenant. A standard lance is usually commanded by an Elite Minor, Elite Major, Brute Minor or a Brute Major and a lance also contains four Grunt Minors and one Grunt Major. A lance of Jackals usually consists and comprises a group of four to six Jackal infantry with one or two of them being Majors and the rest of them being Minors. Jackal lances are sometimes led by an Elite or a Brute.

A lance of Drones is usually a swarm of around a dozen or so soldiers, and are very mobile and always airborne as well as these lances having no command by a Brute or Elite. Science Lances are formed to recover and examine captured technology and is made up of Zealots and led by a Field Marshal.

Legion
A division of many Elite warriors which is often led by a high ranking officer such as a Zealot or Ultra. They are capable of performing tasks ranging from bridge-crew on starships to ground combat.
