is there any online resource about how the germans build their
defensive positions (trenches, log bunkers etc.)

thanks in advance

Here is a thread thats been running for 4 years now, at 71 pages long! It has mostly concrete bunkers from what i've seen, but there maybe pictures in there of them in the build process.
here is the link. Maybe not exactly what you're looking for, but might be helpful.


Cheers,

Cheaky.
