NCO Trait: Justice

Justice is defined as the practice of being fair and consistent. A just person gives consideration to each side of a situation and bases rewards or punishments on merit.

Suggestions for Improvement: Be honest with yourself about why you make a particular decision. Avoid favoritism. Try to be fair at all times and treat all things and people in an equal manner.

NCO Trait: Integrity

Integrity means that you are honest and truthful in what you say or do. You put honesty, sense of duty, and sound moral principles above all else.

Suggestions for Improvement: Be absolutely honest and truthful at all times. Stand up for what you believe to be right.

NCO Trait: Loyalty

Loyalty means that you are devoted to your country, the Corps, and to your seniors, peers, and subordinates. The motto of our Corps is Semper Fidelis!, (Always Faithful). You owe unwavering loyalty up and down the chain of command, to seniors, subordinates, and peers.

Suggestions for Improvement: To improve your loyalty you should show your loyalty by never discussing the problems of the Marine Corps or your unit with outsiders. Never talk about seniors unfavorably in front of your subordinates. Once a decision is made and the order is given to execute it, carry out that order willingly as if it were your own.

NCO Trait: Courage

Courage is what allows you to remain calm while recognizing fear. Moral courage means having the inner strength to stand up for what is right and to accept blame when something is your fault. Physical courage means that you can continue to function effectively when there is physical danger present.

Suggestions for Improvement: You can begin to control fear by practicing self-discipline and calmness. If you fear doing certain things required in your daily life, force yourself to do them until you can control your reaction.
