Each stage has unique religious support requirements. The President of the United States may order the Army to conduct a number of different operations. They range from peacetime missions to general war. During peacetime, the US attempts to influence world events through diplomatic means, and the Army may be tasked to support these diplomatic efforts. Conflict is characterized by hostilities to secure strategic objectives when diplomatic means have failed or are at risk of failing.
War is the use of military force in combat operations against an armed enemy.
Often the Army will operate in the three environments of peacetime, conflict, and war at the same time. Whenever operations in these environments occur simultaneously, the Army integrates and coordinates the effects to accomplish strategic objectives. The Army rarely operates alone. Army units deploy with other military services and agencies of the US government. Increasingly, the US Army operates with other countries as well.
