You will be transitioned into the MINDEF Reserve (MR) once you are no longer liable for National Service. Under the Enlistment Act, NSmen will not be liable for NS call-ups when they reach the statutory age limit of 40 for Warrant Officers, Specialists and Enlistees ( WOSEs) and 50 for Officers. In other words, personnel reaching the stated statutory age limit will no longer be liable to be called up for any NS activities such as ICT, IPPT, mobilisation etc.
