Alright here is a topic, what's your favorite book series?
Mine is Hammer's Slammers by David Drake, its about a mercenary company which gets involved in a myriad of conflicts around the galaxy, each story its them in yet another war, although there are recurring characters like Colonel Hammer, Pritchard or Joaquin, each story usually follows different members of the Slammers (or people having to deal with the Slammers), thing is, its written by a war veteran, and he doesn't shy away from the nitty gritty, a lot of the operations are exactly how a military would do them, and the description of the carnage is exact in the gory details, and some Slammers don't shy away from war crimes.
I like it because I like accurate military operations, and that it doesn't preach at you, it shows you war as it is, and its up to you to come to your own conclusions.
