User:An elite '92/M1029 Ultra-Heavy Walker

The  or the Armadillo is a heavy walker designed for assaults on open terrain. It can carry several Marines and vehicles for insertions into areas where flight is impractical or dangerous. The Armadillo has doors to seal the cabin so that it can be used in hostile environments, much like the EVA Warthog (note: in Halo: New Contacts, these are removed for balancing). Originally, it was designed to be built with overlapping armored panels for greater mobility, hence the name Armadillo, but that proved to be impractical.

Design
The Armadillo has three main decks.

Lower Deck
At the aft end is a ramp for deploying troops and vehicles that can be sealed to pressurize and thermally insulate the cabin (in Halo: New Contacts, it is locked open when deployed). It is protected by a heavy machine gun turret. Near the ramp is a stair running fore to aft, and the mid-fore section is cargo space.

Middle Deck
At the aft end is the main fusion reactor; this is where a boarder must go to disable the Armadillo (although not in Halo: New Contacts). It is designed in such a way that it is powerful enough for the MAC to fire 2 rounds per minute but if it goes critical, it does not damage the Armadillo severely, although all systems will be offline except the machine guns. The mid-section is a corridor-type area, and the front is the control room. From here there are three stairs, one leading down to the cargo hold, another leading up onto the outer top deck, and the third leading up to the anti-air turret and the Hornet garage.

Upper Deck
This deck has an outer walkway surrounding the Armadillo. On the outer walkway on each side are two machine guns (and in Halo: New Contacts, the core at the back to disable the Armadillo). It is accessed from the middle deck through a stair at the fore end which can be sealed in extreme atmosphere (not in Halo: New Contacts). The middle of the upper deck is occupied by the Hornet garage and the stair to the anti-air turret control room.
