A reservist is a person who is a member of a military reserve force. They are otherwise civilians, and in peacetime have careers outside the military. Reservists usually go for training on an annual basis to refresh their skills. This person is usually a former active-duty member of the armed forces, and they remain a reservist either voluntarily, or by obligation. In some countries such as Israel, Norway, Finland, Singapore, and Switzerland, reservists are conscripted soldiers who are called up for training and service when necessary.
