LS1a/CSF-S3b Castel Heavy Ground Type

The LS1a/CSF-S3b Castel Heavy Ground Type is a Garrisai from the *Harbinger* Universe.

## Technology and Combat Characteristics

Using the LANDSTRIKE SIGNA, it is the variant of the LANDSTRIKE indented for use by Castel Ground Types to become the LS1/CSF-S3b Castel Heavy Ground Type. Features two side shoulder-mounted twin 100mm HAMGs, and an Anti-Armor Hammer. It was manufactured in large amounts during the First Age of Mass-Production, with 150 of these systems produced in total.

## Armaments

- 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. These HAMGs are unique to the Heavyarms in that they are mounted on the sides of the shoulders, which can fire in a 360-degree range. Not only do they increase the overall reaction speed of the machine, they also allow for the shouldering of rocket launchers or back-mounted weapons. The guns are equipped with a recoilless slider as to prevent damaging the joints of the Garrisai itself. When not in use, the HAMGs rotate downwards in parallel to the arms.

- CW-06 Rocket Launcher: An alternate heavy armament for most Ground Type Units, primarily used by the UNI (though it has seen use by LCR Garrisai as well). 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).

- Anti-Armor Hammer: A simplified version of the Telescopic Rocket Warhammer that is used for fatigue damage and knocking opponents around the battlefield. Unlike the weapon used by the Megahammer back in the Interstellar Era, the face of this hammer is a more cubical in design to make storage easier.

## History

Alongside the Castel GTs, the Heavyarms were a common sight during a majority of the Second Armeli Invasion and long after the fall of the NDRC. Despite their original faction being reduced to what would be the Lance Core Remnants, it was still seen in the numerous counterattacks launched against the Mercury Legion. However, the increasing loss of units caused the Remnant forces to commonly salvage their Heavyarms units for parts for their other Garrisai. An intact and heavily customized Castel Heavyarms was seen in use by the Desperado Storm Remnants, which had been equipped with an extra Nanolaminate Standard Shield and a Swarmfire Missile Silo over its left shoulder.

## Trivia

- The Castel Heavyarms has a similar function and weapons design to the Dom and Dom Tropen of Gundam.

- Its secondary name "Heavyarms," is based off of the Gundam Heavyarms from Wing, and "Heavygun," the term in the Harbinger Universe for most ace B-Types.
