SEK 99

The SEK-99 is a quadripedal, terrestrial heavy assault walker of the Hierarchy, designed for long-distance heavy fire support. Armed with the powerful SY-51 nuclear x-ray laser, the SEK 99's primary battlefield role is the denial of atmospheric airspace and the destruction of heavy planetary fortifications. It's battery of nine coilguns can provide ballistic artillery support well over the horizon.

Description
The SEK 99 is a heavy quadripedal walker. The main body consists of a superstructure with three major sections: the upper mantle, housing the communications array, navigation station, radar, drone hangars, coilgun batteries and SY-7 anti-air lasers; the central deck, housing the reactor core and central command deck, as well as the S2A missile batteries; and finally the lower mantle, housing the SY-51 nuclear laser and twin particle lances, as well as their auxiliary powerplant and the gunnery deck. The 99 has a crew of 15, consisting of a commander, a navigation officer, a communications officer, a gunnery officer, a chief engineer, a flight officer and 9 enlisted personnel.

The SEK 99's mobility train consists of four traditional mechanical legs, which offer a limited degree of height variation, ranging from 35 m to the walker's full operating height of 75 m. The SEK 99's sheer size makes it a potent terror weapon, and increases the effective range of its heavy directed-energy arsenal, but does increase its vulnerability to concentrated enemy fire. Almost all of the 46 SEK 99 walkers disabled during the Empire-Hierarchy war were essentially mission-killed through concentrated fire on the legs.

The YT-99 Fusion Reactor serves as the primary powerplant of the walker, powering most of its major systems and the primary laser array. Auxiliary turbine generators provide energy for the particle accelerators, while a delivery dish on the upper mantle allows the wireless supply of energy from orbit - this is chiefly used to maintain the Magneto-Radiative Composite Field Emitter, which serves as the walker's primary defense against kinetic projectiles and particle beams.
