“For these reasons, the ‘principle of the object’ will come to have many times its former importance in instruction to all ranks. The need for a clearer concept of it, however, is not greater than the need for junior commanders who will take a keen interest in the larger affairs of war and for higher commanders who make it a practice to get down to their troops. More appropriate to what we will know in the future that to what we have experienced in the past is that old truth: It is not always possible to lead from behind.”
S.L.A. Marshal, Men Against Fire, 1947.
