As a practical matter you can't really do anything until you return to the US. Since Philippines law doesn't don't permit divorce, you will have to do it in the US in either your state of legal residence or the state where you have been stationed for the required length of time (for example, TX allows soldiers to file in TX if they have been stationed there for 6 months). You need to consult your local JAG Legal Assistance Office for more information.
