I briefly studied history in college (before I dropped out), but it was always my first love. And military history, of course, is the ultimate history. In fact, you could almost say that without militaries there would be no history, in a sense.
But this information is generally readily available, you just have to take the time to look for it and do a lot of reading. Of course, any World War II day on the History Channel is required watching.
BTW, since most history is written by the victors, I try to take every opportunity I can to read anything written by the losing side as well. Even when the loser puts out propaganda about why he lost it's still informative.
Me too, I love History in School and University
