Often times, despite good planning, emergencies do happen. If possible it is best to get to the nearest military installation for help. If you are not near a military installation and/or your emergency occurs after hours, contact the nearest chapter of the American Red Cross. You may request Navy-Marine Corps Relief Society assistance through the Red Cross.
The Navy-Marine Corps Relief Society or other service equivalent (Air Force Aid, Army Emergency Relief, etc.) can provide interest free loans or grants to help with emergency needs such as emergency transportation, medical/dental bills, food, rent, disaster relief assistance, child care expenses, and essential vehicle repairs.
The American Red Cross provides social welfare services to needy military personnel and their families. They assist with emergency communications, financial assistance, and help with humanitarian reassignment and hardship.
Remember while traveling to carry important medical papers, prescriptions, and important telephone numbers so that you can contact your sponsor and your next duty station in case an emergency arises.
