Fist thyme per-rousing tis bored.
Pardon I don't recall the author or title of my mentioning however I think the title is 'On Killing'. It's a book by an retired Col. or something and he discusses what it takes to kill. By this I mean he starts out talking about back in the day when growing up in a farming community. The respect of the animal you're raising to slaughter for survival, substanance was of grave importance. I've not read much past there. He does mention how soldiers would usually do things like aim high, to the sky, during early gunfare wars. As a man who's killed, seen killing, studied it, he gives insight on what it's like. Considering your titles I thought I'd mention what I could to recommend this book.
