A merc should look out for his buddies, take care of his gear, and fight for the honor of the unit. Obey the rule's of engagement. Don't poach on another unit's contract. Do the job you're hired for.
An officer should be tough but fair, lead from the front, and look out for his men; an enlisted man should look out for his buddies and take care of his kit. Every soldier should be willing to fight and die for the honor of his unit, service, and country; follow orders; obey the “rules of war”; treat an honorable enemy with respect (a dishonorable enemy deserves a bullet); and wear the uniform with pride.
