The initial deployment phase of the “Unganze” model had seen the massive mecha frequently swarmed by smaller enemies, which pressured the Unaff into complementing their new giant with smaller support units. While the old “Unarze” model suited the role of close to mid-range support just fine, the Confederacy deemed their HWP mechas too old for the job, since the HWP series hadn't seen any major changes for quite some time. In order to provide mid to long-range fire support that was could actually hit smaller and faster targets while still keeping the ability to put hurt on more durable enemies, the Unaff military ordered the HWPs to undergo a wide range of upgrades to bring them up to that time's standards.
The amount of resources poured into the quick development of the model while maintaining quality, and then turning it into a product ready for mass production proved higher than anticipated though, and in the end a great deal of newly designed weaponry got scrapped in the planning phase. Instead, the Untorrha usually wields a mixture of adapted versions of already existing systems for the most part, though the generally good combat performances of the model, especially in the formation it has been initially designed for, could lead to more investments into weapon and support systems in the future.
