As that seems to be your thing I'd recommend the author Wolfgang Schneider, he has some very good books on the doctrinal aspects of the tank forces of the Wehrmacht. Not to mention decent history of process for specifics, such as everyone's supposed favorite the Tiger. Well worth checking out if that's your bag.
Slack was not bad. The drummer was pretty nice, otherwise idk it could have been a lot of bands in that genre. Not slating it, I'm just not really into ambient stuff at the moment.
Too lazy to post links myself at the moment as well.
