What is military law?

Military law only applies to those in military service but is enforced during war and peace. Military law is a statutory code of rules and articles provided by Congress for the government and discipline of troops. Attorneys represent active-duty military personnel, military reservists, and former military personnel with "veteran" status. Military law cases may involve court-martial proceedings under the Uniform Code of Military Justice, and the re-employment rights of reserve military personnel called to active duty.
