In most of its appearance, Uisk and its variants are characterized by high output and mediocre armour. However, its stats are not very consistent in different installments. In Front Mission 3, it was employed as launcher units by the Centipede Mercenary. Later in Front Mission 4, its output was further raised and became a Comms wanzer model. In Front Mission 5, however, its output was lowered and its agility became higher, making it a suitable candidate for Jammers. It was seen deployed by U.S.N. Army as Jammer units. They may be variants of the same model, but this was not explicitly stated.
It has a branch series known as Zelt.
