If you are in the military or Armed Forces, you are subject to military law. If a legal issue arises, you should consult with military law attorneys as soon as possible.
Essentially, the Uniform Code of Military Justice governs military personnel at all times. This means that military law covers both civil issues, such as the processing of security clearance revocations, as well as criminal issues, including drug use and desertion. Whether you need to retain a lawyer for a divorce or you are faced with a military court martial, the use of a military law lawyer is your best bet.
No matter what your legal issue may be, it is always best to seek legal help early in the process. An attorney can help secure what is likely to be the best possible outcome for your situation and avoid both unnecessary complications or errors.
An experienced lawyer should be able to communicate a basic "road map" on how to proceed. The lawyer should be able to walk you through the anticipated process, key considerations, and potential pitfalls to avoid. Once you've laid out the facts of your situation to the lawyer, he/she should be able to frame expectations and likely scenarios to help you understand your legal issue.
