Afterward, it has appeared in every installments to date. It is produced by the Schnecke Corp. of E.C. Germany. Among Front Mission fans, it is more commonly known through its successor line, the "Grille" (German: Grille, Cricket).
Igel and Grille models are largely deployed as sniper units. Due to its precision-based actuator design and responsiveness of the recoil stabilizers in their arm parts, both lines boast very high accuracy ratings when using virtually any kind of ranged weapon. As a result, numerous armed forces and organizations have imported dozens of Igel and Grille models, despite a noted lack of armoring and mobility in their designs. The Igel line and its derivatives are considered the flagship line of Schnecke Corp., with it being commercially successful for more than two decades since its inception in the 2080s.
The popularity of the Igel Eins and Igel Zwei models led to the creation of derivative units, equipped with shotgun weapon arm parts and caterpillar-type legs. These derivatives, while not as popular as the standard bipedal model, saw uses in developing O.C.U. member-states such as Alordesh. The tank-based Igel Eins and Igel Zwei sacrificed long-range combat abilities in exchange for better short-range combat and improved defensive capabilities.
The Igel and Grille lines boasts several variants with a Horn designation (noted as "H" in the unit's naming). The Horn variants are advanced models with slight internal and external changes to provide better overall combat performance than the standard ones, enabling them to fulfill more than just sniper roles. The "H" units are also commonly used by military commanders in the German Special Forces, the Blauer Nebel.
During the introduction of the MULS-P2 standard, the company built a new Grille model which used the Gepard prototypes as a base. The new MULS-P2 model boasted significant improvements in durability and mobility, allowing it to function as assault roles more easily than before.
