In broad usage, the terms "armed forces" and "military" are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. Armed force is the use of armed forces to achieve political objectives. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply "military".
Whereas recruits who join as officers tend to be upwardly-mobile, most enlisted personnel have a childhood background of relative socio-economic deprivation. For example, after the US suspended conscription in 1973, "the military disproportionately attracted African American men, men from lower-status socioeconomic backgrounds, men who had been in nonacademic high school programs, and men whose high school grades tended to be low".
Military law introduces offences not recognised by civilian courts, such as absence without leave (AWOL), desertion, political acts, malingering, behaving disrespectfully, and disobedience (see, for example, Offences against military law in the United Kingdom). Penalties range from a summary reprimand to imprisonment for several years following a court martial. Certain fundamental rights are also restricted or suspended, including the freedom of association (e.g. union organizing) and freedom of speech (speaking to the media). Military personnel in some countries have a right of conscientious objection if they believe an order is immoral or unlawful, or cannot in good conscience carry it out.
Having military intelligence representatives participate in the execution of the national defence policy is important, because it becomes the first respondent and commentator on the policy expected strategic goal, compared to the realities of identified threats. When the intelligence reporting is compared to the policy, it becomes possible for the national leadership to consider allocating resources over and above the officers and their subordinates military pay, and the expense of maintaining military facilities and military support services for them.
The first recorded use of the word military in English, spelled militarie, was in 1585. It comes from the Latin militaris (from Latin miles, meaning "soldier") through French, but is of uncertain etymology, one suggestion being derived from *mil-it- – going in a body or mass. The word is now identified as denoting someone that is skilled in use of weapons, or engaged in military service, or in warfare.
Either because of the cultural memory, national history, or the potentiality of a military threat, the militarist argument asserts that a civilian population is dependent upon, and thereby subservient to the needs and goals of its military for continued independence. Militarism is sometimes contrasted with the concepts of comprehensive national power, soft power and hard power.
The President, Secretary of Defense and other senior executive officials are advised by a seven-member Joint Chiefs of Staff, which is headed by the Chairman of the Joint Chiefs of Staff, the highest-ranking officer in the United States military and the Vice Chairman of the Joint Chiefs of Staff. The rest of the body is composed of the heads of each of the DoD's service branches (the Chief of Staff of the Army, the Chief of Naval Operations, the Commandant of the Marine Corps and the Chief of Staff of the Air Force) as well as the Chief of the National Guard Bureau. Although commanding one of the five military branches, the Commandant of the Coast Guard is not a member of the Joint Chiefs of Staff. Despite being composed of the highest-ranking officers in each of the respective branches, the Joint Chiefs of Staff does not possess operational command authority. Rather, the Goldwater-Nichols Act charges them only with advisory power.
Battlefield commission: under certain conditions, enlisted personnel who have skills that separate them from their peers can become officers by direct commissioning of a commander so authorized to grant them. This type of commission is rarely granted and is reserved only for the most exceptional enlisted personnel; it is done on an ad hoc basis, typically only in wartime. No direct battlefield commissions have been awarded since the Vietnam War. The Navy and Air Force do not employ this commissioning path.
Each branch of the service operates its own Service Academy as a four-year institution of higher education. All students receive a full scholarship with a small monthly stipend. Upon graduation, you're commissioned as a second lieutenant in the Army, Air Force, or Marine Corps or as an ensign in the Navy or Coast Guard. Appointment to a service academy is extremely competitive.
