Grand Strategy was a concept few in history were truly adept at. Bruno, however, was operating on a macro scale. Overseeing and micromanaging multiple theaters of war, all while using the limited communications technology of the early 20th century to do so.
GPS was not a thing, nor were cellar telephones, the internet? If Bruno spoke of such things in this day and age, he might as well be forcing himself to undergo a lobotomy at an insane asylum. It was not like he could access a personal end-user device, and instantly send orders to an entire company of soldiers, informing them of where, when, and how to attack.
However, with his more modern understanding of warfare, especially mobile warfare. Bruno had introduced some specialized troops to the battlefield. While Special Forces were a concept mostly derived as a result of lessons learned from the second world war. One man in this world ultimately knew better.
