BrickTech

BrickTech is a private military company responsible for providing security to contractors and engaging in armed conflict against criminal syndicates, most notably The Notorious.

Security
BrickTech's security primarily focuses on surveillance cameras, armed guards and locked vaults.

Cameras
BrickTech's surveillance cameras are bulletproof and indestructible as a result, they are able to rotate to track suspicious occurrences. BrickTech cameras can be temporarily disabled by camera looping, enabled by the Nimble ability. BrickTech armored cameras replace regular cameras on Extreme difficulty and above.

Guards
Security guards employed by BrickTech carry either the G17 or FiveSeven, and can be seen patrolling a specific route or made stationary, they do not walk forward if they see anything suspicious like civilians. BrickTech guards also carry pagers, which will activate upon the guard's death.

Guards also carry a melee weapon for self-defense. Occasionally, the guard may also be in possession of a keycard, which can open locked doors, disable the camera systems on certain maps, the alarms on Diamond Store. 2 keycards can be used to start the timelock that opens the vaults on RO-Bank and Shadow Raid.

If a guard notices anything suspicious, they are trained to call for backup, raising the alarm.

Military
The BrickTech military is a private division of BrickTech. Referred to as BrickTech Security Contractors, they appear on Extreme difficulty in small numbers, but will almost completely replace FBI Officer Spawns on Nightmare. They carry M4A1 carbines and will melee heisters at close distance. They have Helmet and Chest armor that can be shot off. Due to their tougher difficulty as enemy combatants, they are difficult to intimidate, requiring a heister to slightly damage one to convince it to surrender. Once converted, their aggressive behavior as ally units can prove useful in the heat of battle.

Trivia
