Firebase

The UNSC Firebase is a prefabricated base of operations used by the UNSC Marine Corps in combat zones or locations that are otherwise hostile.

In Halo Wars, a default Firebase costs 500 resources to drop in from orbit, and only provides three construction slots and no turret foundations. It has two upgrades, Station and Fortress.

Overview
The Firebase combines the needs of a tactical communications, a command center and expansion into both a barracks and a production facility capable of assembling combat vehicles. The Firebase unit itself is a variant of the old colony starter units constructed out of polycrete and powered by a small hydrogen reactor. Because gaining a foothold quickly was key to fighting insurrections throughout the colonies, ships can directly deploy the entire assembly unit of a Firebase, making it immediately useful. This ability proved invaluable in the ongoing war with the Covenant and was often considered a key advantage of the UNSC on the ground.

In addition, Firebases are capable of producing unarmed Warthogs, along with the special unit for the selected leader. Firebases were used to great effect at the Human-Covenant War, including the Harvest Campaign, the Battle of Arcadia and the Battle of the Flood-controlled Shield World. Although starting out frail, the structural strength of the command center is increased with the addition of each new Firebase addition, making it a good idea to erect multiple Firebase additions as soon as possible.

Beneath the Firebase there is a large underground garage in which resources and vehicle parts dropped down from orbiting warships may be stored. Also, all Firebase additions such as Reactors or Supply Pads emerge up from this subterranean area, pre-built and fully constructed. Firebases also have self-destruct sequences and lock sequences, the latter of which can be used to deliberately trap one's own newly-trained forces inside the compound.

Station
The Station is an upgraded version of the Firebase, retaining the command center, but adding two more building sites (for a total of five) and four turret foundations.

Fortress
The upgrade allows two other building sites, totaling to seven building sites and the same four turret sites from the station. It also features a self-destruct sequence allowing it to destroy itself for other allies to make a base in its spot and damage any enemy units nearby.

The fortress also allows for a lock sequence that will not allow any newly trained units to leave the base when done training/being produced.

Tactics
Many players use firebases when laying siege to enemy bases, by constructing Barracks, Vehicle Depots and Air Pads, and other similar structures, allowing for the rapid deployment of forces to the front lines. Firebases' self-destruct sequences are commonly used by players to prevent enemies from earning points for the base's destruction, and to allow other allies to replace the base and damage any nearby enemy units. It cost 500 resources and only Forge and Anders can build these. Make sure the area is clear because it can be shot down as it is dropped from orbit.
