it's important to note that I can't provide real-time information on specific policies or regulations. However, I can give you some general information about military emergency leave and how it usually works.
In most militaries, including the United States Armed Forces, emergency leave is typically granted for certain personal emergencies, such as serious illnesses or deaths in the immediate family. Marriage is an important event, but it may not qualify as an emergency for military leave purposes. It is more common for regular leave or vacation time to be taken for a marriage ceremony.
If your fiancée is in the military, he should be familiar with the procedures for requesting leave and the specific guidelines for emergency leave within his branch and unit. It's best to have an open and honest conversation with him about your desires and discuss how you can plan the marriage in a way that aligns with his military commitments.
If he is eligible for regular leave or has accrued vacation days, he might be able to use those for the marriage. In such cases, you wouldn't need to pay for the leave, as it's part of his military benefits. However, if there are extraordinary circumstances that require him to take leave that is not available through normal channels, you should reach out to his commanding officer or the relevant personnel in his unit to inquire about the possibility of emergency leave and any potential costs associated with it.
Keep in mind that military policies can vary, and the best course of action is to have your fiancée communicate with his superiors to understand the options available to him.
