Mexico has no foreign nation-state adversaries and little ambition to impose itself upon other nations. It repudiates the use of force to settle disputes and rejects interference by one nation in the affairs of another. Although it has not suffered a major terrorist incident, Mexico considers itself a potential target for international terrorism.

The Aztec came to establish the Flower Wars as a form of worship, which unlike the wars of conquest, aimed at obtaining prisoners for sacrifice to the sun. Combat orders were given by kings (or Lords) using drums or blowing into a sea snail shell which gave off a sound like a horn. Giving out signals using coats of arms was very common. For combat that took place outside their cities they would organize several groups in which only one was in action while the others remained on alert. When warfare was carried on to cities these were usually attacked in three different parts, or flanks, all at once and in equal numbers of assault groups. This tactic was used in order to know which division of warriors laying siege would distinguish themselves the most in combat.

Recent History: Mexican Drug War

Although violence between drug cartels has been occurring long before the war began, the government held a generally passive stance regarding cartel violence in the 1990s and early first decade of the 21st century. That changed on December 11, 2006, when newly elected President Felipe Calderón

 to end drug violence there. This action is regarded as the first major retaliation made against the cartel violence, and is generally viewed as the starting point of the war between the government and the drug cartels. As time progressed, Calderón continued to escalate his anti-drug campaign, in which there are now about 45,000 troops involved along with state and federal police forces.

In recent times, the Mexican military has largely participated in efforts against drug trafficking. The Operaciones contra el narcotrafico (Operations against drug trafficking), for example, describes its purpose in regards to "the performance of the Mexican Army and Air Force in the permanent campaign against the drug trafficking is sustained properly in the faculties that the Executive of the Nation grants to him, the 89 Art. Fracc. VI of the Constitution of the Mexican United States, when indicating that it is faculty of the President of the Republic to have the totality of the permanent Armed Forces, that is of the terrestrial Army, Navy military and the Air Force for the inner and outer security of the federation.

Organization

The Army is under authority of the National Defense Secretariat or SEDENA. It has three components: a national headquarters, territorial commands, and independent units. The Minister of Defence commands the Army via a centralized command system and many general officers. The Army uses a modified continental staff system in its headquarters. The Mexican Air Force

 is a branch of the Mexican Army. As of 2009 starting salary for Mexican army recruits was $6,000 Mexian pesos, or about $500 US dollars per month, with an additional lifetime $10,000 peso monthly pension.

The principal units of the Mexican army are nine infantry brigades and a number of independent regiments and infantry battalions. The main maneuver elements of the army are organized in three corps, each consisting of three infantry brigades, all based in and around the Federal District. Distinct from the brigade formations, independent regiments and battalions are assigned to zonal garrisons (45 in total) in each of the country's 12 military regions. Infantry battalions, composed of approximately 300 troops, generally are deployed in each zone, and certain zones are assigned an additional motorized cavalry regiment or an artillery regiment.

Regional command

México is divided into twelve Military Regions composed of forty-four sub-ordinate Military Zones [the 2007 ed. of the IISS lists 12 regions, 45 zones], the enumeration is for nominal designation. There is no fixed number of zones in a region, therefore operational needs determine how many or how few, with corresponding increases and decreases in troop strength.

Usually on the secretary of defence's recommendation. The senior zone commander also is commander of the military region containing the military zone. A military zone commander has jurisdiction over every unit operating in his territory, including the Rurales

(Rural Defense Force) that occasionally have been Federal political counterweight to the power of state governors. Zone commanders provide the national defence secretary with socio-political conditions intelligence about rural areas. Moreover, they traditionally have acted in co-ordination with the Secretariat of National Defense (SEDENA) on planning and resources deployment.

Since the early first decade of the 21st century the Army has been steadily modernising to become competitive with the armies of other American countries and have also taken certain steps to decrease spending and dependency on foreign equipment in order to become more autonomous such as the domestic production of the FX-05 rifle designed in Mexico and the commitment to researching, designing and manufacturing domestic military systems such as military electronics and body armor.
