Sentry Gun Kit
A worn light machine gun bolted to a steel tripod, a motion sensor wired to the trigger group, two traverse motors and a car battery to keep the electronics alive. On a powered base grid (150 W) it covers a 150 degree arc out to 45 m and feeds 7.62x54R from its own ammo box. Set it to fire on the infected only, or on the infected and anyone not on the cupboard list. It is loud: every burst brings more of the dead. Needs a claim; a base holds two to four. Use it to place.
