The finest young battalion and company officers that S.L.A. Marshall knew, he explains (in The Soldier’s Load and the Mobilty of a Nation) were men of this type:
They were sedulous in planning and preparation. They made their dispositions painstakingly. They insisted on personal reconnaissance to a point where it nettled their subordinates. Thus they had at all times the feel of their own situation, which is half of the battle. But at the opportune moment they were ready to shoot the works.
Knowing is half the battle. The other half is extreme violence.
You should do a post on “the opportune moment”.
