CSF-S3c/LP03 Centurion Antilockup Type

Technology and Combat Characteristics
The Centurion GT (or Centurion ALT) is a variation of the Castel GT that is designed to operate over uneven terrain. Its armor plating is much larger and layered compared to its normal counterpart, covering up the joints and external areas with a protective rubbery sheet. This is to prevent debris from locking up and stalling the Garrisai during combat based in rough areas. It is also equipped with high-mobility inspired hover thrusters that allow the Centurion to glide over the sand. With its large fuel capacity and ease-of-storage Weapons Binder, the machine is designed to operate under long-term missions.

Armaments
- 100mm Heavy Antimateriel Gun: The Centurion features a single-barrel variant of the 100mm HAMG, which is placed on a 180° rotating base that features a sliding rail. This serves as a recoil compensator, and stores the gun reverse of the forearm when not in use. The reason for the single barrel conversion is to be used as a reduction in weight when moving at high speeds, as well as having a lower chance at a misfire when in sandy areas. It is mounted on the left forearm.

- CW-06 Rocket Launcher: An alternate heavy armament for most Ground Type Units. It is a solid-round (unguided) firing weapon, with a relatively slow projectile speed but a high AoE. The weapon comes equipped with a targeting sight and foregrip by default, though a fixed shoulder mount or an ATS link can be attached when needed. It was modified from the 300mm HPNC and even uses a similar feeding system to the smoothbore cannon. The magazine itself holds up to three Type-Six Conventional Warheads (which is where the CW in its ID number comes from). In the case of the Centurion, it is mounted on the right shoulder, and rotates downward when deployed. When not in use, it is stored vertically.

- Anti-Armor Saber: A longer and heavier version of the Anti-Armor Blade. While retaining a similar quality, the Saber’s length gives it a wider range of attack, and is more capable of slam attacks compared to the blade. It is stored in the Weapons Binder when not in use.

- Disruptor Grenade: Serving as the standard explosives weapon for most Garrisai units, this capsule-like grenade releases a large blast after being activated. It contains sensors that react with Nanolaminate Armor, allowing for them to roll and bounce normally on surfaces, yet explode when coming into contact with an enemy (similar to glass grenades). Smoke, Stunlock, and Flare variants are available to pilots depending on the mission.

- 40mm Assault Rifle: A staple of the Kestrel Line, the 40mm Assault Rifle (or ASU) has been adopted by almost every faction due to its versatility and reliability in combat. Almost always seen being used by Mass-Production Units, the Rifle can be modified to fit any situation. Attachments such as underbarrel Grenade launchers, extended magazines, bayonets and flashlights are only some of the things the weapon can equip.

- KT-300 High Powered Naval Cannon: Also known as the Smoothbore Gun, the 300mm HPNC is a toned-down version of the 500mm MPNC that fires ballistic shells. Due to its smoothbore style barrel and sheer stopping power, it is only effective at medium range. However, its shells are AoE and don’t require a whole lot of accuracy, thus a user can fire it into the general vicinity of enemies at a distance and still have a good chance of hitting something. Originally used as a battleship-mounted cannon, it was eventually broken down into a single, shoulder mounted weapon for Garrisai. Contains a three-round internal magazine. Replaces the CW-06 Rocket Launcher when equipped.

- 60mm Carbine: Being a less common alternative to the 40mm ASU, the 60mm Carbine is a weapon more tailored towards infantry marksmen instead of general soldiers. Featuring an adjustable scope, semi-automatic receiver and recoil compensator, the weapon is perfect for accurate and powerful shots. The only problem with the Carbine compared to the ASU is its staggering capabilities. Since it relies more on precision instead of fire rate to attack enemies, the pilot cannot attack the body of the Garrisai, and instead aim for its joints or head camera. This makes it difficult to use, but in practice, invaluable in battles. A three-round burst fire receiver is also available should the pilot using the weapon choose one.

Special Equipment and Features
- Weapons Binder: A staple of the Centurion ALT that would become the rough basis of the Artillery II's Weapon Binders. They are capable of holding the Saber, Rifle, and Grenades in skeletal racks that keep the armaments secure. It is mounted on the left side of the backpack when equipped, and can be purged if needed.

- Thermal Visor: A piece of equipment unique to this series of machines. Compared to the usual spotlights given to most Mass and Limited-Production Types, the Centurion was given an advanced visor to remain relatively covert when on long-distance operations. The lack of visible light meant that only the sound of these machines could be easily detected.

- External Fuel Canister: In order to prolong the Centurion's operation time, external fuel canisters filled with Dechalus were often attached to these machines' Fusion Drives. This ensured that patrols could be made in quick time without the fear of consuming too much energy. They are mounted under the backpack, with tubes connecting to the internal frame. Centurions that were equipped with these canisters were occasionally classified as the Centurion Extended-Use Type.

History
Much of this machine's history comes from operations in the sands of Cassiopeia, where they were deployed in moderately large numbers from the Citadels of Frontier Point and Midnight Base. This was to allow for the Castel Ground Types to maintain the urban areas of Decholon, the Nautica Aquatic Types to maintain the seas, and the Cyclops/Juggernaut Ground Types to be interspersed among them. Eventually, many Centurions were reassigned to the snowy areas of Draco and the marshlands of Andromeda, in which their usual Desert Colors were replaced with Winter and Forest colors, respectively.

During the Fall of the NDRC, many of these machines were sent to the upper areas of Decholon to push back the Mercury Legion. However, the disconnect from their intended use not only caused them to struggle in the close-quarters of cities, but also leave the desert areas of Cassiopeia completely unguarded (among the other regions in which they were deployed). Years later, the remains of a few of these machines were used to construct a small army of damaged Garrisai. This included the Corinthian, who took advantage of the Centurion's superior mobility thrusters over open terrain as their main form of defense.

Trivia
- The Centurion ALT shares some similarities with the Dom Tropen and Desert Gelgoog from Gundam.
