Even in running, sports theory and theoretical training lectures are needed to reach all possible potential. You will have to think on how you place your foot onto the ground and in which way you role the sole in both 100 meter Olympic sprint and silently trespassing different terrain.
The actual time on a firing range or in an empty compound to hunt preparing for combat is way overestimated, while indirect training is hardly understood by any Germaniced force, because they are actually busy dominating their position within the ratpack.
