Presently, there are 12 "Military Regions", which are further broken down into 44 subordinate "Military Zones." In both cases, a numbering system is used for designation. There is no set number of zones within a region, and these can therefore be tailored to meet operational needs, with a corresponding increase or decrease in troop strength. Today the army consists of 230,000 combat-ready deployable ground troops.
Chief among the independent troops is an Army Corps consisting of two mechanized infantry brigades located in Mexico City, with a full complement of combat and support troops. In addition, there are two brigades of the Corps of Military Police, Special Forces units, Presidential Guards (another motorized brigade), and a parachute brigade.
All these independent troops are located in Mexico City where they act as a ready reserve and as centers of excellence.
At one time, a special "Rural Defense Corps" (or "Rurales") played a role similar to a traditional popular militia, but the role of the "Rurales" has been greatly diminished in recent years.
Officially, as there is no Minister of Defense, the Mexican military's two components are not under command of a single, unified forces commander at any level below the President, who has a military role under the national constitution: Supreme Commander of the Armed Forces (Comandante Supremo De Las Fuerzas Armadas). According with the Constitution of Mexico the President is the only Army five-star general. (This is comparable to most other countries with a presidential system of government, such as the United States.) Instead, a Minister, who is a serving officer — an Army four-star general or a Navy admiral — heads each component. Each minister serves in a dual capacity: as a full cabinet member reporting to the President, and as the operational commander of his branch, but because of politics and rank, the navy is subordinate to the army.
Moreover, the Air Force commander and his staff are embedded to Army headquarters; an Air Force officer never has risen to the hierarchy's most trusted, senior positions. This subordination has allowed the Army to identify its organization as the "Secretariat of National Defense" (Secretaría de la Defensa Nacional — SEDENA), resultantly, (to the Navy's annoyance) the current army chief, General Guillermo Galván Galván (and his predecessors) holds the nominal title of "Minister of Defense".
The President picks the ministers who do not necessarily have to serve as such for his entire presidential term (sexenio, sexenium, six-year term). During the PRI's single-party rule, ministerial selection was a strict, pro-forma exercise by seniority. However, both Presidents Ernesto Zedillo (1994–2000) and Vicente Fox (2000-2006) strayed from precedent and reached down to the junior levels to select "more progressive" officers to lead the forces.
The Army and the Navy are regionally organized, with central, national headquarters in Mexico City and subordinate, regional headquarters. Historically, this has proved effective, as the military's main deployments have been domestic. Troops are stationed throughout the country to serve as continuing presence of authority and to allow for immediate critical response. Dispersion by regional military zones has facilitated local recruitment of non-commissioned officers (army sergeants, navy petty officers) and enlisted men and women, allowing them to be stationed near family during their military service, an important cultural consideration. On the other hand, mobility is expected of commissioned officers, moving from assignment to assignment and to the military center, in Mexico City, giving them much experience, and, historically, preventing any senior officer from remaining too long in one place and developing a personal power base through local allegiances, and so becoming too powerful as a war lord.
Per a defense ministry report by General Guillermo Galván Galván, the army has 181,356 active duty soldiers, about 0.16 per cent of the population . Its 1989 budget was 0.7 per cent of the Gross Internal Product (GNP). In 1999, Mexico's military budget increased to 0.9 per cent of the GDP, to US$4.0 billion. Since the year 2000, however, with the economic boost that the country has experienced, the defense budget was decreased to 0.5 per cent of the GDP, and currently has annual expenditures of US$10.062 billion (2007). Since President Calderón assumed office (December 2006), he has submitted legislation increasing the budget, in order to fight the drug war against the narcotics cartels, and narcotic drug trafficking in general, that have extended their violent business to each corner of the country.
According to the CIA World Fact book, Mexico's available military manpower is 20,000,000 (males age 18-49, 2005 est.), with 19,058,337 males fit for military service, and 1,063,233 males annually reaching military service age. Since 2000, women have been allowed to volunteer for military service. Currently, Mexico's armed forces number some 620,400, including the reserves. Mexico's military is in two branches, the National Defense Secretariat (Army and Air Force) and the Navy Secretariat (Navy, Naval Air Force, Marines).
The Mexican Army works around three preparedness missions, or plans:
DN1: Preparation of the military forces to repel external aggressions. No military armed force can leave Mexican territory without a declaration of war, and approval of the Congress. The last time this was invoked was in 1942, to send an expeditionary force to the Philippines, after war was declared against Germany and Japan, following the sinking of two Mexican ships by U-boats. In 1990 President Carlos Salinas de Gortari asked the permission of the Congress to send troops to the Gulf War, but it was refused, since there was no declaration of war against Iraq.
DN2: Preparation of the military forces to protect the internal security of the country. This would include police actions against guerrilla forces, counter-drug operations, and, originally, political control. Up to 1970, the Mexican Army had been used as a repressive force to maintain the virtual dictatorship of the single-party PRI government. The most controversial use of the military had been called "The dirty war" in the 1960s, which included the 1968 Tlatelolco massacre of students and unsuspecting bystanders. After 1980 these types of operations had nearly completely ceased (see EZLN).
DN3: (Defense against natural disasters) The Army should always be ready to help the civil population in case of disaster. This includes preventive measures. For example, between August and November, military forces are sent to Mexican coastal areas to aid the public in the event of hurricanes or floods. For the Mexican people, the DN3 plan is the most important peacetime operation of the Army. The Army provides food, shelter, medicine, and medical services to the people that need them. This also includes reconstruction of roads and communication services. Because calling the implementation DN3 plan is an acceptance of severe problems, the DN3 plan was not invoked in the 1985 Mexico City earthquake that left large areas of Mexico City in ruins, since the authorities did not want to recognize there was an emergency in the capital, while the army was called to the city, it was just a peacekeeping force. This later became a severe questioning on the government. Also, the Mexican Army provided aid to the US when the hurricanes Katrina and Rita occurred to help the people in need.
Each year, the SEDENA (Secretary of National Defense) requires every eighteen-year-old man and every man who will be that age within twelve (12) months of the draft date of a designated Clase de Servicio Militar Nacional (National Military Service Class) to report to his municipality's designated military recruitment center. There, he will register to the conscription program with his birth certificate and standard-size, head-and-shoulders portrait photographs in order to be issued a precartilla (pre-military identity card) with a serial number, photograph, right thumb fingerprint, weapons licence number, and personal data (address, current schooling level, etc.) that finally, after the draft lottery and a year of service, earns him full conscript status and a Cartilla de Servicio Militar Nacional (Military National Service Identity Card), informally, cartilla (military I.D. card) attesting to his having fulfilled his civic obligation in duty to the nation. The SEDENA's lottery determines who will be exempted from or drafted for military duty — either with the army or with the navy.
Formerly, the military service lottery required the presence of every man of a National Military Service Class; he stood at attention, awaiting either conscription or exemption; each man's name was called aloud and a child drew a colored ball from a bag — the color determined the man's conscription to or exemption from military service. Today, military service status selection is computerized, but the results are announced as before: White ball (Army service), Black ball (exemption), and Blue ball (Navy-Marines service). Currently, a seal is stamped to the "precartilla" identifying the bearer's military draft lottery status.
The drafted men attend and participate in week-end military training comprising basic military training with weapons, and combat tactics, yet it emphasises education, history, physical fitness, and military discipline for one complete year. Afterwards, the precartilla (pre-military identity card) is returned to the conscript with an added page certifying his status as having fulfilled his national military service and identifies the military branch, the unit, rank, etc. The document then acquires full status as the Cartilla del Servicio Militar Nacional (Military National Service Identity Card), informally Cartilla; this status is recorded to the National Defense Secretariat files.
This document (Military National Service Identity Card) is an important form of Mexican national identification, and its existence is almost always requested by private and public employers, however, this identity document has ceased being required for obtaining a passport for international travel.
The military colleges are not universities, yet provide significant technical training applicable to civil employment after military service. They emphasise military ethics (honour, duty, country), history, discipline, physical fitness, and the perpetuation of the military as a societal institution. The armed forces provide university-level education through the War College (Colegio de Guerra) in Mexico City, to which officers must attend and earn a Diplomado del Estado Mayor (DEM) degree to qualify for promotion to general officer or admiral rank.
Legally, every Mexican man is obligated to a year of servicio militar nacional — SMN (national military service — NMS), generally only a few hours of drill on weekends, not true military training. Most conscripts will have received only one marksmanship session at a rifle range by the time they have completed their NMS obligation. The 1986 National Military Service class was the last class oriented to social service purposes. The NMS was restructured, and conscripts now receive true military training and education. The 1987 class was the first to receive proper marksmanship training. The men of an NMS class who remain after their obligation, are recruited volunteers who have chosen to be career soldiers.
Article 129 of the 1917 Political Constitution of the Mexican United States establishes that: No military authority may, in time of peace, perform any functions other than those that are directly connected with military affairs, but the Army's temporary replacement of civil police forces, in specific cases, before the creation of the Federal Preventative Police has been much debated in the Congress and in the mass communications media; (cf. U.S. Posse Comitatus Act)
Like-wise, per Article 16: No member of the army shall, in time of peace, be quartered in private dwellings without the consent of the owner, nor may he impose any obligation whatsoever. In time of war the military may demand lodging, equipment, provisions, and other assistance, in the manner laid down in the respective martial law; (cf. Third Amendment to the United States Constitution)
Article 13 of the Mexican Constitution specifically provides for military jurisdiction over all military crime and indiscipline; military tribunals execute jurisdiction over military personnel, per the Uniform Code of Military Justice (UCMJ).
Regarding military personnel labour conditions, discipline, and the chain of command as fundamental to the military, Article 123-B establishes: Military and naval personnel and members of the public security corps, and personnel of the foreign service, shall be governed by their own laws. this is correct
As the President of Mexico is Commander in Chief of the armed forces, the chain of command and military discipline are subordinated to him. The military obey him and maintain low public profiles in politico-military debate; they serve, they do not rule.
In recent decades, the mass communication media (television and print) were restricted in their coverage of the military's ranks and their activities. Only in the 1990s have Mexicans become publicly aware of the activities of its army, navy, air force, and marines. Since 1995, they are under much domestic and international public scrutiny, given the challenges inherent to greater national political openness, transparent public fiscal accountability, and results from missions pursued.
The current defense ministers, General Gerardo Clemente Vega and Admiral Peyrot, are considered progressive and academic in nature and background, though they remain in the monolithic image of the Mexican military man. The Mexican public have little insight to internal debate and dialogue with national military institutions; in public relations terms, both the Army and the Navy continue being reactive rather than proactive.
There is a specific element of the Mexican Army which takes care of the President, a special group known as the Estado Mayor Presidencial (equivalent to the American Secret Service). Every member of this division is an expert marksman and has tough training for the protection of the President.
As of 2005, intervention in UN peacekeeping operations is being discussed, but with the current political composition of the Congress, it is unlikely to be approved, as according to the Mexican Constitution, no military armed force can leave Mexican territory without a declaration of war.
