In this study, we examined the current status of suicide prevention and interventions by analyzing mixed materials collected through surveys and in-depth interviews. Fifteen military support counselors who are currently working in the military base participated in the in-depth interview.

Also, units which include suicide related questions in counseling application form are 10(66%) and the units provide suicide related questions to client at their initial interview are as many as 13(87%). The interventions done by military support counselors to highly likely suicidal client were such as report to chain of command, cooperate with military hospital, notice clients guardian, provide counselors personal contact number at the most. Difficulties that counselors face are identified by 4 factors : ‘military's lack of interest and short of support’, ‘absence of suicide risk intervention system’, ‘social recognition’, ‘counselor factor’ and 11 categories. Among them, general categories are shown as ‘hush and glare’, ‘short of counseling budget and specialized staff’, typical categories are shown as ‘absence of cooperative organization’, ‘absence of corresponding manual’, ‘lack of interest and negative attitude toward counseling’, ‘naive attitude toward suicide’, ‘burden and anxiety the counselor have to deal with’, ‘poor suicide preventing education and training’, ‘exhaustion caused by suicidal risk intervention’ and so on. Also, Future development proposed by counselors are classified by for 4 factors : ‘improve military's interest and support about the issue’, ‘establish suicidal risk intervention system’, ‘social recognition’, ‘counselor factor’ and 11 categories. Among which, general categories are ‘budgetary expansion and hiring more professional manpower’ and typical categories are shown as ‘improving problem recognition’, ‘24/ on-call system’, ‘establishment of unit and community network’, ‘development of suicide risk intervention’, ‘compulsory suicide prevention education’, ‘education and training for counselors’, ‘mutual support between counselors’. Based on the results of the study, we discuss ways to prevent military base suicide and suicide risk intervention and give proposals for follow-up studies.
