Zaigaut and its variants are frequently characterized by extremely high evasion and mobility but very weak armour and is most commonly used as recon units. Its variants also typically has the ability to roller dash silently, as shown in Front Mission Online, giving it extraordinary abilities to infiltrate enemies' defense line and therefore carry out reconaise missions. It was used by the Zaftran Army and O.C.U. Huffman troops as recon units.
It also seems to have a branch series named Zaigs, as seen in Front Mission 2 and Online.
