Individual skill in marksmanship is an advantage in battle only when united with fire discipline and control.
Constant movement to the front lessens the effect of the enemy's fire. Modern battles fought in the open show that the heaviest losses are in the mid and long ranges. When close range is reached the losses diminish rapidly.
The best protection against artillery fire is a constant but irregular movement to the front. When close to the enemy's position his fire is least effective.
A knowledge of how to use the bayonet and the will to use it must often be the deciding factors in battle.
Finally:
In training we can not go far wrong or fail to accomplish the best results if we keep before our minds the spirit as well as the wording of paragraph 352 of the Infantry Drill Regulations: "The duties of infantry are many and difficult. All infantry must be fit to cope with all conditions that may arise. Modern war requires but one kind of infantry—good infantry." Cavalry, dismounted, should be as efficient as infantry under all conditions of service.
Section 2. Combat.
The field of battle is the final test of the instruction, discipline, and efficiency of the fighting force of any army.
The squadron is the attack unit or the defense unit, whether operating alone or as part of a regiment. The troops constitute the firing line and the support.
An individual soldier is concerned only with the enemy in his immediate front, in obeying orders, and instinctively doing what he has been trained to do.
