The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
The 70 millimeter Stalker Turrets were stationary Landstalkers made by DreadZone. They usually had to have a EMP deployed on them to take out their shields, so Ratchet could destroy them. They attacked by shooting lasers and Landstalker mortars at you. In high difficulty modes they were extremely deadly because they did lots of damage and rarely missed.
They were also extremely useful for training the holo-shield on, as long as you kept a shield out at all times. During this it is best to either not deploy an EMP, or to let your bots die. When you are down to two shields, place one when the previous is failing and retreat to an ammo/weapon vendor. Then slowly return, using shields as cover.
