Young able-bodied male Singaporeans are required to undergo national service. The majority are able to cope with military training without developing any psychological disorders. A small group, however, are unable to handle the rigours of military training. They are identified, diagnosed and managed appropriately so that they can continue to serve national service within their capability. Three types of psychological disorders are highlighted in this paper. Type 1 cases refer to those with psychotic and neurotic disorders and they are usually downgraded to serve in non-combat vocations. The severe psychotics are exempted from service. Type II cases refer to those with stress-related disorders which are temporary conditions amenable to treatment. Many of them can return to their previous functioning level once their stress-related problems are resolved. Type III cases refer to those who capitalise on their existing physical conditions by complaining or exaggerating their psychological symptoms hoping to prolong their medical condition so that they can get an easy way out. These cases, which are in the minority, require firm handling, limit-setting and counselling so that they can learn to address their problems appropriately without resorting to psychological symptoms. Emphasis is given to the diagnostic approach and treatment of all 3 types of disorders, particularly the stress-related disorders. The roles of unit personnel and family members in providing a corroborative account of the servicemen's behaviour, work performance and inter-personal relationship are given special emphasis in the management of soldiers with psychological problems.
