Saving this little tidbit because its time to let the rest of the entry die
The MG-42 is used by a number of witches. In the 501st JFW, It is used by Trude, Erica, Minna and Eila. The MG-42 as depicted in the series is slightly but significantly different than the weapon as it actually was; it uses a saddle drum magazine based on that of the MG-15 (This is similar in apperance to a Beta C-mag). Aircooled variants of the MG-15 were issued by the Luftwaffe with this type of magazine. However, the MG-15 is a top feeding system while the MG-42 feeds from the side; the saddle-drum type magazine blocks the ejection port of the weapon.
