Final answer:
Soldiers are not allowed to earn leave in certain situations, such as during war or when they are involved in disciplinary issues. They may also be restricted from earning leave if they have reached their maximum allowable days.
Step-by-step explanation:
Soldiers are not allowed to earn leave in certain situations. For example, during war, soldiers may not be granted leave as they are needed for duty and to ensure the safety of the nation. Additionally, if a soldier is involved in a serious disciplinary issue or investigation, they may be restricted from earning leave until the matter is resolved. Furthermore, soldiers who have reached their maximum allowable leave days may not be able to earn additional leave until their balance is reduced.
