All depends on interpretation...a StuG was an assault gun (SP armored artillery piece) while the Jagd were armed with PaK weapons or modified KwK weapons. Since this one's mounting the 12.8cm artillery gun complete with the muzzle brake (vs. say the PaK/KwK version in the Jagdtiger), the StuG designation fits from that technical aspect. Have to agree though that when you look at it, the design screams "Jagd" and not "StuG" to me!
