When West Germany rearmed in the 1950's the Bundeswehr based its armament on the German experience in WWII. It wanted a fully armored fighting vehicle (Schützenpanzer) for its infantry. The result was the HS30 IFV introduced in 1958.
It proved to be a poor design. Throughout its career, it suffered from technical troubles and by 1965, with the introduction of the Leopard tank, it also became tactically obsolete, because it was too slow to follow the Leopard cross-country. In 1971, the much better Marder IFV was introduced, though various versions of HS30 continued in service until 1981.

Micro Armor Mayhem has some photos of this model on his website (scroll up a bit).

This model consists of 5 HS30 miniatures on a sprue. They are unpainted and buyers will have to add gun barrels from thin wires or bristles. The turret is fixed.
