Slovenia is a country of 2 million residents at the tip of the Adriatic Sea. Until the 1990s it was part of Yugoslavia, which declared itself socialist but was never part of the Warsaw Pact. As a country between the eastern and western blocs, it cherished the idea of people's resistance. The ideal was that the whole society would act as a defensive force, the prevalent part being involved in civil defense. The concept also called for regular training. After Slovenia's secession from Yugoslavia, the principle of profit precluded most of the training. Industrial policy of maintaining minimum stocks of supplies at hospitals resulted in reduced reserves for response to any mass-casualty disaster. Only recently, thanks to effortless popularization of preparedness for Medical Response to Major Incidents (MRMI), was the European Society for Trauma and Emergency Surgery prompted to urge local medical societies to introduce necessary planning and training. Slovenia started (after 20 years) again to prepare courses for training a swift and correct response in case a of mass-casualty disaster. The introductory symposium was in March 2009, and in February 2010 the first true MRMI course was organized. To reduce costs, give instructors more training, and yield as much as possible from the available equipment, we renewed contacts with the Croatian medical society and worked together in organizing national MRMI courses.
