Mystifying use of bad German in books (by military people)

Did you ever notice those weird german sentences authors use in their books? There are lots of officers who start using german for no real reason I can understand.
I don't know whether you, dear reader, have ever read anything from that genre, but if you have you must have noticed the random german in them, especially common when combat draws near or they are already in the middle of something bad.
Things like 'nicht scheisse'. To all the military authors out there: no shit does NOT mean 'nicht scheisse'! It's supposed to be 'kein Scheiss'. Really. Ask any random german out there!
Therefore my plead: Stop it. It's not cool and even if german sounds hard and dangerous to most people there is no reason to cripple the poor language like that.
Oh and just in case you wanted to know: Germans usually don't argue in in the middle of the street en masse even if it sounds that way. Germans generally don't argue outside. It can be confusing, I guess, but that's just the language.
Anyway: The abuse of an innocent language is really stupid. Please stop putting google translations into your work. Ask somebody who has mastered it to do the translations even if it may be almost as hard as latin and much more confusing. Which is why you can't use google.
Ok, I must confess that I do laugh a lot when I read hopelessly confusing sentences in the middle of the most threatening situations in those military books. Those situations are among the best practical jokes I know.
But if they are after the main action and everything's in ruins and then this majors says 'Jetzt wir sind gehend zu Hause' it just kills the moment.
That's the sentence that made me write this article by the way.
I don't know whether anybody understood this sentence but I guess what they wanted to say was 'Now we are going home'. Unfortunately the german version of it is just crazy. The words can be translated that way, but they shouldn't. Basically it means that they are already at home and they are walking around. Plus the order is messed up.
If you know any authors like that please tell them to stop messing up their great books that way.
