I would be aiming for a German victory in WWI, the Allies had their chance and screwed up.
A German victory in WW1 would be ideal here, but I believe that you wouldn’t need to bring and weapons back with you, just a history book, and point to the few mistakes Germany made and say, “ok, now don’t do that, do this instead”.
If I had to choose a weapon though, i’m kinda torn. On the one hand, bringing back the StuG III would be great to help the Germans break the dead lock without a doubt, but I wonder how well German industry could support them once they went into action, long enough to break the front? Maybe. On the other hand, if I were to bring back the MG42, I know that German industry could support and and keep these weapons running, meaning longer usage and a greater chance of this weapon tipping the balance for a German victory.Â
Awesome points, the MG 42 would have shredded Allied ranks between the lines.
