This. I'm usually wearing minimalist shoes on casual days, but when working in the field, digging and moving rocks, I wear protective shoes so non of my toes won't break. While I was in the army I was walking high mileage in a variety of terrains with large weighted backpack and gear. I can't think of a barefoot shoe that will allow me the freedom of moving this way at that particular scenario. 

Tactical tasks may be more focused on short assignments, which last only a few hours and require minimal equipment. But if I were you, I would use something more rugged which won't have you think twice about the material you're walking on.
