Recruitment
In NDU, NSFs and regulars are expected to undergo the same training before they are qualified to become frogmen. Recruitment begins with a vocational assessment, whereby NSFs are selected among the thousands that enlist each year. Prior to being even selected for the vocational assessment, physical fitness results and medical records are being evaluated and only the best are selected. Basic requirements are perfect eyesight, which explains the absence of people wearing spectacles in NDU, and tip top health condition, not suffering from any chronic illnesses that might jeopardise their training, such as asthma. From then on, the selected few will undergo a battery of tests in the camp, amongst them, water confidence as well as psychological evaluation. Those that meet all of these stringent requirements will then be selected to the NDU, which takes precedence over all other units and formations in Singapore.
