sentry gun
Self-targeting defensive weapon
A sentry gun is an automated weapon system that detects and fires at targets without direct human control.
In military contexts, these are defensive installations that use sensors to identify intruders.
The term appears frequently in video games, where players deploy sentry guns as stationary defenses: I placed a sentry gun to cover the hallway.
