Ultra Heavy Assault Platform

The Ultra Heavy Assault Platform (UHAP, or You-Happy) is an assault walker designed for frontline combat on contested worlds. Sporting a diverse and impressive array of weapons and towering an impressive 31 meters over the battlefield, UHAPs are generally the first vehicles into combat when commanders can procure them.

History

After the Battle of Hoth and the unacceptably high AT-AT losses resulting from it, General Veers knew that he needed a better assault vehicle. He immediately requested a transfer to Imperial Research and Development. There he drew up preliminary plans for what would later become a rare and devastating Imperial Remnant combat unit. Veers, recognizing the AT-AT's strengths, decided to base the UHAP off of the AT-AT chassis. Once the plans were finalized by a team of expert engineers, they were sent to Kuat Drive Yards to construct a limited prototype run of 24 UHAPs. The top Imperial brass liked the intimidating walkers, and ordered them to be put to the test in real combat. General Veers then directed this prototype UHAP division in a battle against heavily armed and well trained rebel sympathizers (a.k.a. mercenaries) on Sintos IV in the Mid Rim. Without any additional support besides two squads of Scout Troopers on speeder bikes, the sympathizer base was totally destroyed. In addition, once the battle was presumed won and the UHAPs were being loaded back onto the ships, another force of mercenaries initiated a surprise attack. With only two UHAPs left unloaded, the force was beaten back with an estimated 34% casualty rate. Due to the Battle of Endor and the unfortunate circumstances arising from that engagement, all funding for the UHAP program was cut only a month after the test run on Sintos IV. Years later the Imperial Remnant would discover the UHAP technical plans and 3 surviving UHAP prototypes in an abandoned warehouse on a backwater Imperial resupply world. The Remnant forces put the vehicle into limited production and fielded them as heavy hitters in a few campaigns against the Yuuzhan Vong.
