CSF-S3b Castel Ground Type

Armaments
- Nanolaminate Ballistic Shield: A basic handheld Shield that blocks most physical projectiles. Its simple design and ease of storage means it’s reliable in most situations, and it can even store melee weapons or missile launchers on its underside.

- 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. They have also been seen in use by the UNI in the form of a compact Submachine Gun.

- Anti-Armor Blade: The Standard melee armament for most mass-production units. It is made entirely of steelpoint Alloy from Blade to grip, thus its durability is incredibly strong. Most times it can be stored on the rear skirt armor, though it can also be stored under a Nanolaminate shield for quick access in a pinch.

- 300mm 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.

- 100mm Heavy Antimateriel Gun: Being Kestrel’s first attempt at portable heavy weapons, the 100mm HAMG is a twin-barreled, alternating Cannon that contains a ten-round internal magazine. Being versatile in almost every range due to an advanced rifling barrel, it requires little skill to use the weapon and the payoff when using it is very rewarding. Its alternating fire means that the barrels remain cool when firing consistently, and extended magazines or belt feeds can prolong the amount of rounds it can fire. When not in use, some forms of the HAMG can fold horizontally between the two barrels, up onto the top of the receiver. This reduces the chance of a misfire when operating the other functions of the Garrisai. A single-barrel variant is also common, 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. Can also be mounted on the side of the shoulders (Megahammer) and even chest mounted (Hammerhead), though these variants are less common.

- 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.

- 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.

Special Equipment and Features
- Searchlight: Most Castel GTs are equipped with spotlights on various parts of their armor to adapt to nighttime conditions. Night Vision optics are also an option for more advanced units, though these are seldom used from their cost alone.

History
The Castel Ground Type is the main design for mass-produced units used by the LCDM. Using the limited data from dormant Garrisai used in the FGC, as well as the frames of the Drax Service machines, the CGT was born. While being structurally lighter and more efficient than the Harbinger Ground Types, they suffered in having stable armor and powerful weapons. On top of this, despite nearly coming up to par with the Revolta Ground Types developed by the Mercury Legion, the LCDM's lack of experienced pilots put them at a severe disadvantage. Compounded inversely with the few experienced pilots being given poorly operating Garrisai kept the LCDM in shambles at the closing of the invasion. It was proposed by DTRO member Robert Castel.

Trivia
- The Castel GT, alongside the Revolta GT and Insurrectionist GT, are the three main "grunt" units in the Post-Interstellar War Era. The CGT in particular shares a resemblance to the role of the GM in Gundam.
