Does anyone know what the correct translations are for the German vehicles? I would like to know if there is a complete list of vehicle names and their translations Example;
Wespe - Wasp, is this correct?

I am not an expert by any means.

I believe that SP guns had insect type names like Wespe=Wasp; Grille=Cricket; Hummel=Bumblebee; I also think Nashorn is some type of beetle. I also think grasshopper was a type of SP gun (Heuschrecke).

I know later tanks/AFVs were named after cats like Tiger(II), Puma, Luchs (Lynx), and the heavy tank Maus=mouse. Also the tank destroyer Elefant (originally Ferdinand) is elephant in English. I also have an assault gun by Alan called the Bison and I think Hetzer is a type of birddog or hunting dog. The Brummbar is their word for brown or grizzly bear.

I think they went to naming their vehicles once war broke out and they were no longer hiding their AFVs behind the "Special Purpose Vehicle" SdKfz title.

Here's some more that Rob missed,

Nashorn = Rhinoceros
Hornisse = Hornet (I seem to recall it was the early name for the Nashorn)
Marder = Marten (as in Pine Marten)
