Turret

From HammerWiki

A turret is a special type of engineer "pet" that is summoned using one of the engineer turret skills. Each type of turret has a different set of abilities, but all turrets share some common traits.

• Turrets function just as any other pet in the game (though they are stationary). You can give them specific targets and commands, as well as setting them to automatically attack, defend, or sit passively.
• An engineer can have only one turret at a time. If a new turret is summoned while another is still active, the old one is removed.
• Turrets can be attacked and destroyed. Their number of wounds depends on their level.

Some skills, tactics and morale abilities affect turrets.
