Many Bolters attacked Halvo Bay under the orders of General Karn. However, like many Locust during the attack, they had little to no protection against enemy attacks, unlike those seen later in the War. They also carried different pistols every time they appeared, probably because there weren't many Drone classes during the beginning of the Locust War and only diversified once they began to retrieve all kinds of equipment which they needed to handle and to give a rank to each class. They appeared at Seahorse Hills, Onyx Point, the roofs near the Museum of Military Glory, and inside the courthouse where Kilo Squad was being trialed by Col. Ezra P. Loomis. Apparently, one of them ambushed the Colonel himself and tried to use him as a Meat Shield before being killed by Pvt. Garron Paduk.
