The Barrelion was developed as an artillery-centric Armored Module, capable of providing long-range bombardments to support frontline units. Similar to the Lion, it was designed with a simple structure for ease of maintenance and cost reduction. Aside from flight, the Tesla Drive mounted on the Barrelion is also used to deploy a T-Dot Array covering the mecha's outer armor, increasing its defensive capabilities. Compared to the TFF's Schutzwald, which was built around the same concept but was rejected due to maintenance difficulty, the Barrelion is more suitable for mass-production. For example, while the Schutzwald's legs are for traversing terrain, the already flight-capable Barrelion's "legs" are solely for landing and securing its posture when firing on ground, reducing complications.
Since Armored Modules in general utilizes physical weaponry, they are capable of carrying more ammunition, while also maximising damage through supersonic propulsion of lightweight projectiles. Though the Barrelion's shooting trajectory suffer from interference when operating within atmosphere, the effects are reduced with the implementation of an invisble T-Dot Array barrel extending from the main barrel, thus increasing bullet velocity. As the Barrelion was created solely for long-range artillery support, it wasn't even equipped with any close-range interception weapons when it was first rolled out. A Twin Beam Cannon was later installed on the Barrelion's hips as a countermeasure, but the mecha's vulnerability in melee combat is still apparent, especially against the versatile Personal Troopers. Nevertheless, the Barrelion, along with its variants and sibling units, proved to be an indispensible combat force of the DC during the DC War, as well as in the hands of the Terra Federation during the L5 Campaign.
Variants of the Barrelion include the V and Custom models, along with the enhanced Heavy Barrelion.
SRW OG1/SRW OGs1[]
The Barrelion was mass-produced by Isurugi Heavy Industries and fielded in large numbers by the DC, as well as the United Colony Corps during the DC War, though their deployment was rather late. As the war ended, the TFF's Mass-Production Gespenst Mk-II were in shortage, leading to the incorporation of a large amount of surviving Armored Troopers into the Terra Federation Forces, with AM pilot training being quickly undertaken to be on time for humanity's great offense on Nevi'im: Operation SRW.
SRW OG2/SRW OGs2[]
Following the L5 Campaign, the Federation gradually replaced Armored Modules with the new-generation Mass-Production Huckebein Mk-II. Though outdated, the Barrelions were still employed by DC remnants.
SRW OGG[]
Though outdated, the Barrelions were still employed by DC remnants.
2nd SRW OG[]
Though outdated, the Barrelions were still employed by DC remnants.
Armaments[]
Missile Launcher (ミサイルランチャー)
Missile launchers mounted on the forearms.
Twin Beam Cannon (連装ビームキャノン | Rensou Beam Cannon)
Clamp-shaped beam cannons mounted on the Barrelion's hips, meant for enemy interception at close to mid-range.
Big Head Railgun (ビッグヘッド・レールガン)
The Barrelion's primary weapon, a giant large-caliber railgun mounted on its main body. When firing, a T-Dot Array field is deployed extending from the barrel to increase projectile velocity.
