In spite of the fact that the suicide rate in Lithuania decreased during the past years, it is still one of the highest in Europe. 1 to 1.5 thousand people commit suicide in Lithuania every year. In 2006, the suicide rate was 30.9 per 100,000 people. Men commit 84% of all suicides. The number of male suicides is six times higher than that of female suicides. Men of average age living in rural areas have the highest risk of suicide. The ratio of attempted suicides to committed suicides is 10:1. Official data on suicide in the Lithuanian Armed Forces has existed since 1993. There have been few suicide cases in the Lithuanian Armed Forces since then. The amount of suicides are spread nearly equally among conscripts, officers, and non-commissioned officers. The suicide rate ranged from 0.15 to 0.34 per 1,000 servicemen for several years. Since 2004, the rate remains more or less level and does not exceed 0.2 per 1,000 servicemen. There is a need for suicide prevention measures, both in the country and in the Armed Forces, in spite of the fact that suicide rates in the military are not as high as in the civilian population. Suicide prevention measures should be applied not only to conscripts but to military professionals as well as officers and non-commissioned officers who are deployed. Scientific research findings [1] have shown an above average prevalence of suicidal behavior among servicemen, a low level of knowledge about suicide, inappropriate attitudes toward suicide, and a positive view on suicide prevention in the military, which became the background for the Program of Psychological support in the Lithuanian Armed Forces. The Program, with a wide spectrum of prevention measures, include: training, education, psychological support for servicemen and their families, additional care of personnel with psychological problems, and/or the risk of suicide, and monitoring of servicemen's psychological wellbeing, is in progress. The efficiency of this program is now being assessed. Since 2006, incident handling for service personnel by psychological support professionals has been organized not only in Lithuania but in the mission area as well. The concept of psychological support for service personnel and their families across the deployment cycle was validated and is now being successfully implemented.
