It is corporate policy to invest in life insurance for each and every one of its valued employees. In event of accident causing injury or permanent system failure, dependants will receive insurance benefits in an order as noted by form CSF-312.

Guards are enemy units who protect corporate facilities. There are various types of guard, with different abilities and characteristics; the number of guards and the types of guard in a facility depend on the corporation and the mission difficulty, as well as the mission type itself and the game difficulty setting. Guards are classified roughly according to their relative danger to the player, with “Common”, “Elite”, “Lvl 2 Elite” and “OMNI” guards appearing at progressively higher mission difficulties.

Agents can attack guards, but the guards in any facility will usually outmatch the agency in raw firepower; so hiding from guards or distracting them is often a better option than fighting. It is therefore important to understand guard behaviour.

Most types of human enemy, including civilians, have a vision range of 8 tiles in a 45° arc, and a peripheral vision range of 10 tiles in a 90° arc; they can also hear noise.

Most guards are armed with guns, so they can overwatch and shoot agents or other agency-controlled units, dealing lethal damage at range. Armed guards can also breach doors, destroying the door and knocking out any agent on the other side. Many guards have armor.

Civilians. They're working late, aren't they? Maybe we should… interrogate them.
—Monst3r

Civilians are unarmed enemy units which occur in some missions. Civilians cannot attack, and cannot become alerted; in a situation where a guard would normally become alerted, a civilian panics and flees the facility via the nearest guard entrance.

	Civilian	Class	Armor	Movement	Description
	Financial Executive	—	—	8 AP	Appears in Chief Financial Suite missions.
	Scientist	—	—	8 AP	Appears in Program Compile side-missions, and the OMNI Foundry Lab mission.

Drones are robotic guards. Some drones are weaponized, but others can still see agents or otherwise detect them, potentially bringing other guards to investigate. Many drones occur only in Sankaku facilities.

Most types of drone have a vision range of 8 tiles in a 90° arc, and no peripheral vision. All drones except Pulse Drones have local scanners, which scan for agents in a radius of 4 tiles, ignoring soft cover. Drones have no hearing, so noise does not distract them, though noise can alert drones by triggering a nearby Sound Bug.

Drones are mainframe devices, so they have firewalls which can be hacked. When a drone is hacked it becomes temporarily controlled by the agency; controlled drones give the player 360° vision from their location, and can be moved by the player. Weaponized drones can be controlled to shoot other guards, or to shoot Security Cameras; Akuma Drones can also be controlled to destroy doors. When the program Leash is installed, hacked drones remain controlled for one turn longer.

Drones reboot when they return to the enemy's control after being hacked, or can be rebooted by EMP damage. A rebooting drone can be pinned to stop its reboot timer from counting down. All drones except Pulse Drones become alerted after they finish rebooting. Camera Drones and Pulse Drones are “EMP vulnerable”, meaning they are destroyed by EMP damage instead of rebooting.

Drones cannot be knocked out, but can be destroyed using lethal weapons.
