Requisition and tech upgrade structure.
Armory structures contain advanced manufacturing modules and electronic support measures that unlock structure, training time, and population capacity upgrades. Construction of an Armory allows the requisition of UNSC Spartans and Operatives to the battlefield. as well as deployment of the Condor gunship. These are key facilities for a UNSC field commander, though their full potential is only unlocked once sufficient resources are available.
The Armory contains specialized machinery and robotic assemblers needed to support the logistical upgrades Isabel has added to the Spirit of Fire, as well as additional communication and sensor systems to expand the force commander's option when assembling battle groups.
