I am looking for a text with particular emphasis on important and relevant military events and battles, and their constituent factors like the strategy and tactics, terrain, classification and evolution of weapons, composition of troops etc. To expand on the title, it would be favorable if this text encompasses all three shogunate eras(Kamakura, Ashikaga, Tokugawa), although I wouldn't mind any single era either.

For some context, I am already reading a related book( Warrior Rule in Japan by Marius Jansen), but it focuses particularly on the governance and feudal aspects over the three eras, rather than the core military aspects I was looking for.
