This issue of the Revista Científica General José María Córdova (Colombian Journal of Military and Strategic Studies) pays deserved homage to the men and women who participated, 200 years ago, in the independence of Colombia, the defense of national identity over the Spanish colonial domain, and the construction of the national strategic culture.

The year 1819 was witness to great events that changed the history of Colombia and that remain in the memory and heart of all the country's children. Simón Bolívar's speech before the Congress of Angostura, the exploits of the liberating army during the crossing of the páramos of Pisba and Paya, and the self-denial of the Juanas, wives and mothers who accompanied the emancipating soldiers, worthy representatives of the Colombian woman, are just a few modest examples of the conviction of a determined people that persisted in their beliefs.

Equally, the acts of loyalty, courage, and sacrifice of the cavalry charges of León de Apure and José Antonio Páez, and the battles of Pantano de Vargas and Boyacá, highlight the importance of the leadership, discipline, and cohesion of the liberating troops that like the glorious National Army of Colombia, at the present time, fight untiringly, in spite of countless obstacles and adversaries, in the defense of the sovereignty, independence, and integrity of the national territory and the constitutional order, as well as in the protection of the human rights of all citizens.

Through five articles that make up a special dossier, we offer original perspectives on neogranadine republican military thought, the foundations of Colombian democracy, the defense of General Nariño in 1823, the military health of the Liberating Campaign, and the classical republican tradition. In the traditional sections of the Journal, we present five manuscripts that explore the dimensions of irregular warfare and how to counteract it; the separation between security and defense in Argentina; the case of sexual violence in the post-conflict zones of the Central African Republic; the integration of women in the labor market of public accounting; and environmental management in companies that generate hazardous waste.
