Tower

The stronghold is a type of military base employed by the Banished, notably used by the mercenary organization to occupy Installation 07 after defeating the UNSC at the Halo in December 2559.

Deployment method
The stronghold is a pre-built structure that is dropped from a Banished vessel in orbit onto the surface of a planet, Halo installation, or other celestial body. Upon impacting the ground, massive spikes on the underside of the structure burrow deep into the terrain and act as a sturdy foundation.

Operational history
After the UNSC's defeat at Installation 07 circa December 13, 2559, the Banished forces led by Escharum occupied the installation. These strongholds were deployed across the ring to maintain control, and would later become obstacles for the UNSC forces led by John-117 to overcome as they fought to stop the Banished in the months that followed.
