The peacetime soldier’s principal task is to prepare effectively for the next war. In order to do so, he must anticipate what the next war will be like. This is a difficult task that gets continuously more difficult. German Gen Franz Uhle-Wettler writes:

At an earlier time, a commander could be certain that a future war would resemble past and present ones. This enabled him to analyze appropriate tactics from past and present. The troop commander of today no longer has this possibility. He knows only that whoever fails to adapt the experiences of the last war will surely lose the next one.
