Contact

"We've got contacts...lots of them...but they're not Covenant...they're just tearing through us...what the!...ooooohhh...nooooo!!"

- Corporal Lovik

In military parlance, a Contact is an encounter with the unit that results or amy result in an engagement. Though the term was originally more commonly used by British and Commonwealth soldiers during the 20th and 21st Centuries, UNSC Marines have come to use the term.

There are three general types acknowledged by the UNSC:
 * Enemy - where the target can be positively identified as an enemy unit.
 * Unknown - where the identification of the unit is difficult to determine.
 * Friendly - where the unit can be identified as "friendly" to UNSC forces.
