OCTSS*
The Anti Unification Alliance's version of the "Destroid", which has a complicated variable system.

* Translator's note: as indicated on the sheet.

Aircraft Explanation
OTM information was obtained by the military businesses that belonged to the nations in the Anti Unification Alliance's sphere of influence. Moreover, the Oktosu is one of the weapons that were developed in the midst of the flow of information that was seized on the Destroid series, a new style land warfare weapon that the Unified Forces side was in the midst of developing. The Oktosu has a complicated, large-scale variable system and is said to have transformed from a submarine into an assault-landing tank and carried out land warfare. The Oktosu was born as a practical weapon after having an unexpectedly smooth development progression. Even though production was limited to a small number because of such things as the high production cost, the Oktosu has a toughness where it was still alright in combat even if there were a few breakdowns. The Oktosu was said to have accumulated the trust of many soldiers in battle.

Data

Height: 11.2 m (land warfare four legged form)
Fully Loaded Weight: 55.15 t
Power: Underwater use High Capacity Fuel Cell Cluster / Land use Diesel Turbo Engine x1 (exchanged for a reaction turbine in later models).
Underwater Speed: a maximum of 40 kt (later models are 45 kt)
Underwater Cruising Depth: 250 m (design pressure resistance depth is 375 m)
Ground Movement Speed: maximum 45 kmph when on foot, 95 kmph when walking on wheels

Caption: The Oktosu has a transformation system that rivals that of Variable Fighters of the Unified Forces. In addition to cruising, the Submersible Cruising Form of the Oktosu also easily handles hand-to-hand combat. The Ground Warfare Four-Legged Form demonstrated a high manoeuvrability that made it possible for the Oktosu to also penetrate forested areas.

Operation Record
The Oktosu was jointly developed by the Daimler Hyperspace Company and the Rubin Central Bureau for Marine Engineering. It is the same generation of weapons as the Unified Forces Destroids, Cheyenne, and so on. After the No.1 craft rolled out in 2006, 92 were produced by the time that the Unification War ended. The later models, which were produced after the development of a small-sized reaction engine, had an improvement in movement performance by exchanging their engine for a reaction engine. In addition, the surplus engine power made it possible for the Oktosu to operate Energy Conversion Armour, and its defensive capabilities greatly improved.
The main battlefield of the Oktosu was the coastline. The appearance of the Oktosu approaching the coastline, commencing with the Mayan Island landing operation, frequently confirmed each front of the Unification War. Even in combat, it demonstrated great fighting strength. Furthermore, after the end of the Unification War, the Unified Forces restarted production of the Oktosu, and until the destruction of the production line in the First Interstellar War, an additional 28 units were produced.

Caption: After approaching the coastline of Mayan Island at a dash, the Oktosu transformed into Land Warfare Four Legged Form and promptly carried out the landing.

Caption: The Oktosu composed the main force of the Anti Unification Alliance's Landing Force. Due to their bombardment, Mayan Island was changed into a sea of fire.

Ground Warfare Four-Legged Form
As armaments, the Oktosu is equipped with twin 12.7 mm beam machine guns above the cockpit, a 57 mm rapid-fire cannon on the right side of the cockpit, and an 8-tube missile container on the left side that can also be used underwater. Moreover, such armaments as an anti-personnel machine gun are installed in the bottom of the vehicle. In land warfare, the Oktosu was operated as a four-legged style multi-legged gun battery.

A: Bifors 57 mm Multi-Purpose Rapid-Fire Cannon
B: 12.7 mm Beam Machine Gun Turret
C: 8-tube Missile Launcher
D: Anti-Personnel Machine Gun

Caption: The Ground Warfare Four-Legged Form of the Oktosu can be called a mobile gun battery. It is furnished with wheels on its four legs for high-speed movement on level ground. During land warfare, it can walk on the wheels at 95 kmph. Also, even though the later period model's horsepower was improved, the land speed itself doesn't appear to have changed.

Around the Cockpit
The cockpit is positioned below the 12.7 mm twin beam machine gun turret. The hatch consists of double doors for getting on and off the Oktosu. Also, an additional machine gun can be set next to the cockpit.

Caption: A part of the unit when seen from the side. Although the transformation system is a complex one, it isn't one that required elaborateness, like a VF.

Submersible Cruising Form
When in the Submersible Cruising Form, the legs fold up into a tear drop form for less resistance. Main power drives the water jets with a high-capacity high-power battery. Furthermore, the maximum speed increases in the later period model that's equipped with a reaction engine, and the restrictions on its endurance disappeared.

Caption: The Unified Forces recognized the excellence of the Oktosu, and even after the end of the Unification War they continued to produce the Oktosu for a long time as a special-forces craft. The reaction engine equipped later period model was said to be especially popular on the scene, as its survivability was also high with its armour having been changed from composite armour to energy conversion armour.

Caption: The front of the hull when in submersible cruising form. The parts that become the foreleg in Ground Warfare Four Legged Form have a horse-power that can hold a heavy load, and amounts to a jumbo manipulator that can also be used as a striking weapon.

Caption: A large camera is installed in the forefront of the hull in submersible cruising form. Searchlights are installed on both sides of the lower part of the camera. The peripheries of the camera slide around the camera when transforming and so on.
