March 01, 2021 Lianhe Zhaobao SINGAPORE - More national service enlistees will soon be able to take on operational roles within the Singapore Armed Forces (SAF), regardless of medical fitness, as the organisation reviews the way it classifies their fitness for different vocations. This is as the SAF introduces new vocations and redesigns existing ones in response to a changing threat environment, such as having cyber specialists to protect key digital networks and systems, Senior Minister of State for Defence Heng Chee How said during the debate over the Ministry of Defence's (Mindef) budget on Monday (March 1). "We are redesigning our Medical Classification System (MCS) and the Physical Employment Standard (PES) System to shift away from the binary classification of combat-fit versus non-combat-fit deployment," he said.
