Military Discipline is a state of order and obedience existing within a command. It involves the ready subordination of the will of the individual for the good of the group. Military discipline is an extension and specialized application of the discipline demands habitual but reasoned obedience that preserves initiative and functions unfalteringly even in the absence of the commander. Discipline is created within a command by instilling a sense of confidence and responsibility in each individual.
Discipline demands correct performance of duty. The need for discipline is best inculcated in individual by appealing to his sense of reason. In the few instances where appeal to reason fail, the use of punishment is effective in causing a recalcitrant individual to conform and perhaps appreciate the need for discipline. Condemnation and earned praise from senior to his subordinate, either individually or collectively, for tasks well done serve to strengthen the disciplinary bonds which bind together the smooth functioning team.
Max Anders says, "Only the disciplined ever get really good at anything." Everything in life requires some sort of discipline. Whether it is hitting a baseball, climbing a mountain, playing a musical instrument, making good grades or brushing your teeth it all comes down to a matter of discipline.
"The core of a soldier is moral discipline. It is intertwined with the discipline of physical and mental achievement. Total discipline overcomes adversity, and physical stamina draws on an inner strength that says drive on." - Former Sergeant Major of the Army William G. Bainbridge
Self-disciplined people are masters of their impulses. This mastery comes from the habit of doing the right thing. Self-discipline allows Army leaders to do the right thing regardless of the consequences for them or their subordinates. Under the extreme stress of combat, you and your team might be cut off and alone, fearing for your lives, and having to act without guidance or knowledge of what’s going on around you. Still, you—the leader—must think clearly and act reasonably. Self-discipline is the key to this kind of behavior.
In peacetime, self-discipline gets the unit out for the hard training. Self-discipline makes the tank commander demand another run-through of a battle drill if the performance doesn’t meet the standard—even though everyone is long past ready to quit. Self-discipline doesn’t mean that you never get tired or discouraged—after all, you’re only human. It does mean that you do what needs to be done regardless of your feelings.
