On the online store (it is the only place I have seen it but it may be in other places too) the models for the Jagpanzer 38(t)have the title "JagdPanzer 38 tonne Hetzer" implying that the "t" in 38(t) stands for "tonne" or that the tank weighs that much. The "t" in jagpanzer 38(t) doesn't stand for tonne, it stands for tschechisch which is the german word for Czech, as the hetzer was based on the Panzer 38(t), a Czechoslovakian tank. It also doesn't make sense as the Hetzer does not weigh 38 tonnes but around 16 tonnes (which they also say in the description). This post is very nit-picky but it confused me when browsing the store. If there is a valid reason for the name to be "JagdPanzer 38 tonne" then I will be happy to accept it, I got most of this information from quick searches online. I just thought it would be best to be as accurate as possible 😀.
