military system

John Deere is an old historian of the military, what he has studied for most of his life, everything related to military strategy and tactics as well as the weapons used throughout history, but at the age of 80 he is on his deathbed, but for unknown reasons to reincarnation in another world with a military system, but which is limited by the era, what did you expect tanks and aircraft carriers just starting out? ha! It's more fun as cavemen try for a heavy load of hair. well that is the best synopsis that I do in my two minutes as a writer xD well hopefully this is not a disaster.
