A United Nations heavy battlesuit, the refinement of one of the earliest UNA suits, which was originally designed in Germany by EurAlloy GmbH in the late 1970's. Production was moved to the United States after the fall of the Federal German Republic in 1978, and the suit has seen many revisions in its design, though it is outwardly almost unchanged.. This is not a typical combat unit, as it's slow and cumbersome compared to the Canadian-built Nordyne Regulator, which is what you see on the ground with 6-Commando. However, there are some environments where the Regulator is not as useful: high pressure and aquatic environments, extreme heat and cold (the Antarctic, for example), areas of high radiation or extreme biohazards, or in hard vacuum. Given the increased threat of atomic warfare between the UNA and the Odessa Compact, the GPzKpfZ-22 is seeing increased distribution, and Regulator suit operators are being extensively cross-trained to use both suits, in case of radiological or other combat emergencies.
