First Army Corps / Primer Cuerpo del Ejército /
1er. Cuerpo del Ejército ICE

Midway into the Miguel de la Madrid Hurtado administration (1982-88), the National Defense Secretariat (S.D.N.) proposed a major reorganization of the army that shifted the focus on structure away from political considerations and more towards operational features. This new structural plan proposed reorganizing the long-standing military zone system into a more tactically-suited corps organization. Although this reorganization sought to reshuffle the 36 military zones into seven corps, by the time de Ia Madrid left office in 1988 only one corps could be considered fully functional, while another two had only a skeleton headquarters. The new S.D.N. administration (1988-94) remained committed to the reorganization, but it made minimal progress in implementing the planned changes. It seeme unlikely that the restructuring process would continue, and in fact it did not.

As of 2006, chief among the independent troops was the First Army Corps consisting of two mechanized infantry brigades located in Mexico City, with a full complement of combat and support troops, including the Special Forces of the First Army Corps [Fuerzas Especiales del Primer Cuerpo del Ejército]. The First Corps Special Forces [Primer Cuerpo de Fuerzas Especiales] are the Special Forces units associated with the First Army Corps, formations which are also termed First Special Forces Corps [Primer Cuerpo de Fuerzas Especiales], though this later formulation does not imply this existence of a Corps of special forces. These units have no territorial responsibility, and have the flexibility to operate anywhere in the country, but their roles and missions are the same as those of the units assigned in the territorial control.

In 2003 the Federal Institute of Access to Public Information received an appeal for review filed by the appellant, challenging the answer given to the following request: "I request the judicial review denial of access to information by SEDENA. How many and what Independent Infantry Brigades are part of the First Army Corps and how their deployment in the country?." While they can not give information on the demarcation of these units, there is no impediment to respond to the part of: how many and what are the Infantry Brigade INPD as part of the Army Corps?".

The Ministry of Defence based its response and classification as proprietary information, Article 13, Section I of the Federal Transparencia y Acceso a la Información Pública Gubernamental, y en el Octavo [Transparency and Access to Public Government Information, and the Eighth], Décimo Octavo fracciones I, IV y V, y Vigésimo de los Lineamientos Generales [Eighteenth fractions I, IV and V, and twenty of the General Guidelines] for classification and declassification of information of the agencies and entities of Federal Public Administration.

The Government took the position that this part of the military deployment, authorized by the President of the Republic to meet any eventuality that may endanger national sovereignty or alter social peace, as the First Army Corps is the strategic reserve of the country, thus revealing the capabilities of this Gran Unidad Superior [Superior Large Unit, literally "Upper Great Unity" implies providing strategic military deployment information, authorized by the PRESIDENTE DE LA REPUBLICA MEXICANA, to meet any eventuality that disturbs the peace, tranquility and the internal order of the country, therefore, information requested is classified as confidential for a period of twelve years. In granting this request, the applicant or persons who seek information could deduce the amount of weapons, materials and equipment used by the troops can therefore estimate their operational capabilities and logistics, thus endangering the lives and safety of the elements of the Forces Armadas, and that lawbreakers would be able to anticipate to hinder or block military activities aimed at maintaining peace, combating drug trafficking, armed groups and organized crime, therefore, it was considered high risk to military activities. This understanding that the concept of strategic deployment from a military standpoint, is the preparation and conduct of all activities aimed at maintaining order, which can not be improvised and must be constantly planned, therefore, the deployment is intended to prepare Fuerzas Armadas to respond effectively and in coordination to the maintenance of public peace, disasters and other similar eventuality predictable, affecting peace, security and internal order.

As regards the Third Report of Work 2002-2003, cited by the appellant, including the Chapter on "Organizational Structure" to the First Army Corps [Primer Cuerpo del Ejército], which is part of Major Units and Special Forces [[las Grandes Unidades y Cuerpos Especiales], this Instituto found that the organic structure is reproduced in the website la Secretaría de la Defensa Nacional, as has been fulfilled with Article 7, Section I of the Federal Law of Transparency and Access to Información Government Public Information. The requested information is classified.

The arrival of the 1st Army Corp [I CE - 1er. Cuerpo del Ejército] does not imply the presence of all their forces, in this case was only present 65º Battalion of Infantry. It does not imply either that it was the time first that appeared in the state of Chiapas. As it indicates this description, 1er. Cuerpo del Ejército can operate at the same time in any zone of the national territory. The left sleeve of the military uniform acquired the following.
