Military Intelligence Day is observed in Russia and Armenia every November 5, commemorating the establishment of the Registration Agency, the first military intelligence agency in post-revolutionary Russia. This day marks the anniversary of the Revolutionary Military Council's approval of the agency in 1918, which later evolved into the Intelligence Department of the Red Army Staff. The main role of military intelligence is to collect, analyze, process, and disseminate information to assist military commanders, and its operations are conducted year-round, regardless of peacetime or wartime conditions. In Russia, military intelligence is represented by the Main Directorate of the General Staff of the Armed Forces, while Armenia's intelligence activities are managed by the National Security Service. Celebrations typically include various events recognizing the contributions of military intelligence personnel in both countries.
