What signifies that leave is earned in a military context?

In a military context, leave is earned based on the amount of time served. This means that service members accumulate leave days depending on their length of service, which typically translates to a certain number of days of leave for each month served. This accrual method allows military personnel to earn a specified amount of leave annually, which can be used for personal time away from duty.

Unlike liberty, which may be granted under different circumstances and does not necessarily accumulate over time, leave specifically involves a formal accrual process tied to service duration. This distinction highlights the importance of service commitment in determining the amount of leave a service member earns throughout their career.

The other options do not accurately reflect how leave is earned. For example, while leave can be available after training or during deployments, these factors do not define the process of earning leave itself.
