Turret/doc

Turrets can be found guarding various government installations in the world, though most turrets found outdoors nowadays will be milspec turrets. Turrets are present in the top level of a science lab if the player enters without an ID card (i.e. with explosives); they despawn silently for authorized staff. Individual turrets can later be found in science lab computer rooms. Police roadblocks also deployed several 9mm turrets.

The player can deploy her or his own turrets. See inactive turret. A (hostile or friendly) turret affected by EMP (such as from EMP grenade) will turn back into inactive turret and drop unused ammo (9mm). If destroyed by damage instead, it will explode (radius 1) and drop 1 component (scrap, electronic or 9mm).

They can attack up to 24 tiles with their SMGs and can eviscerate targets at close range with up to and more than 50+ damage per shot (And it'll fire multiple times a turn to boot), it's debatable whether or not it's actually broken, considering that it'd be easier to punch an entire horde of zombies to death than to walk towards a turret under any circumstance.

(Some?) Turrets will warn the player by beeping loudly before attacking.
