LS1/MESS-S1aF-003 Landbuster Harbinger

Technology and Combat Characteristics
The Landbuster Harbinger, as the prefix of its name suggests, is a combination of the LANDSTRIKE and Buster Harbinger equipment sets. Its weaponry is nearly identical to that of the LANDSTRIKE, with the only difference being the Factory Buster still being intact. Using a LANDSTRIKE System allows for said system (and any weapons attached) to be purged at will, reducing the weight of the machine its attached to.

Armaments
- 100mm HAMG: Refitted onto the LAND STRIKE System from the Buster Harbinger, this 100mm HAMG has slowly worn down over time. It can allow for close to medium-range attacks using a repeating barrel. Similar to its use on the Buster Harbinger, it can be folded in half horizontally on top of the forearm.

- 300mm HPNC: Taken from the armory of Neptune base, this long range AoE Cannon is incredibly powerful as a special attack in most cases. Similar to how it was used by the Standard Harbinger, the cannon can rotate backwards attached to the right shoulder joint.

- Striker Missile Silo: A 6-tube Striker Missile launcher mounted on the left shoulder joint, it can be paired with a lock-on system to ensure it hits its mark. After being depleted, it can be stored on the unit’s back or be purged off of the LSS. The weapon provides medium-to-long range heavy attacks.

- Retrofitted Factory Arm Attachment "Factory Buster": Since the Factory Buster was still mounted on the left arm joint and viable as a weapon, it was kept. It is a close-quarters claw device that can be used for offensive, defensive, and supportive roles. It is able to latch onto and break enemy machinery, is large enough to serve as a makeshift shield, or can even be used as a maintenance tool for non-combat oriented roles.

- Swarmfire Missile Launchers: The Landbuster is equipped with four Swarmfire Missile Launchers—two on the side skirts, and two on the ankles. Each contains a total of twenty small missiles that can be used to envelop an enemy in a fiery blast. When activated, the hatches covering the missiles swing out, allowing for them to be launched. The launcher assemblies can be purged when depleted.

- Folding Heat Blade: Serving as the Landbuster’s backup melee weapon, the Folding Heat Blade is compact enough to be stored comfortably on the rear skirt armor. This allows for continued close-range attacks should the Factory Buster become disabled. Its heated blade can melt right through Nanolaminate Armor, so it is very effective in most anti-Garrisai combat.

- Anti-Armor Knives: Just like the Harbinger’s previous forms, a pair of Anti-Armor Knives are stored within each of the machine’s calf armors. They are only available after the Exo-Armor is purged, meaning they should only be used as a last minute weapon. They are capable of penetrating the internal frames of Garrisai if placed right, but other than that they should be used sparingly.

- 60mm Carbine: Being the Harbinger’s weapon of choice when it comes to ranged combat, this semi-automatic weapon is extremely deadly in the hands of skilled pilots. Perfect for most engagements outside of an immediate range, this weapon serves as the Harbinger’s primary form of attack in battles.

Special Equipment and Features
- LAND STRIKE SYSTEM: Similar to the first LSS used by the Harbinger earlier in time, this second version of the system was created with the same idea in mind.

History
In preparation for the Battle of Midnight Base, the aging Buster Harbinger was outfitted with another makeshift LAND STRIKE System to compensate for its worn down arsenal. The system itself was given to the Buster Harbinger from the Neptune Remnants. Sporting Missile barrage capabilities, a 300mm and 100mm Cannon duo, as well as the Factory Buster already attached, the Landbuster was invaluable in pushing through the seemingly impenetrable defenses of Midnight Base. Only after losing its LS System and Factory Buster was the machine too damaged to continue the fight, and was subsequently replaced by the Perfect Harbinger via a TGDP. It was then recovered but never repaired.

Trivia
- The Harbinger's Landbuster Pack pays a slight homage to the Full Armor Gundam (Thunderbolt Ver.), as well as the Strike Rouge Ootori.

- The prefix “Landbuster” combines the names of the Harbinger's previous two forms—the LAND STRIKE Harbinger and Buster Harbinger.

- Its prefix is also a nod to Landmaster of Star Fox.
