In the entire inventory of the LUNAR armed forces cira 2480 there is only one Heavy Axel, which itself is an experimental design. LUNAR, largely satisfied with the armed forces expressed in the OU-8 and OUS-10 platforms didn't see the need to produce an expensive unit when the medium designs already performed admirably in the face of the second UEPC invasion attempt in 2477.
Still, as an expected exercise in curioisty LUNAR went forward with a prospected heavy Axel design to test the limits of their design capabilities. The final unit, developed at Romer Peak, was to be called the OUK-20 Agirga. It is remarkable in the history of Axel design in that the unit is a six-legged walker. Typically this had been avoided in the past due to pilot confusion, but here it was implimented by LUNAR designers as a means to create a stable gun platform for the twin rail cannons that comprised the main armament of the Agirga. It was also intended to mount the same saddle-equipped weaponry sported on the OUS-10 and occasionally on the OU-8.
Only ten of these units were constructed as a pre-production test. LUNAR's collective defense commanders decided not to puruse a production plan with the Agirga, and two units each were sent to the major colonies on the front face of the moon.
During the Third Invasion attempt by the UEPC, the OUK-20 had a chance to finally prove itself athough not on the first day of combat. Both stationed at Colombo crater were destroyed by their crews to prevent capture by the UEPC. It wouldn't be until the fierce fighting at Clavius base when the OUK-20 really shone as a terror on the battlefield in its native environment. The hexiped design, in the hands of a masterful pilot, is just as manuverable as an OU-8 and the unit can reposition itself within minutes. Coupled with the zero recoil of the heavy rail cannons, the OUK-20 became a nightmare to the UEPC set against it.
Whew! Just got CS5 and trying to get re-adjusted to tablet use with the software. They seem to treat pen pressures different, and nobody told me about the two buttons allowing the pen to govern size and pressure! These were innate features in CS3.
