The Baltics were one of the most important lines of defense for the Soviet empire, the extreme western bastion, so the concentration of troops here was enormous. It is believed that Latvia was the most militarized territory in the world at that time. The exact number of military personnel is unknown, various sources mention 200,000 to 350,000 at different times. In 50 years alone, 3,009 troops were deployed in more than 700 locations in Latvia. One such place was the USSR army base in Marciena.
