A State Guardsman provides free health care services to a Rio Grande Valley resident during a humanitarian mission Aug. 1, in Laredo, Texas. The mission, known as Operation Lone Star, is an annual event that provides free medical services to people along the Texas border. More than 400 Texas Military Forces service members, 200 state and county employees and numerous volunteers collaborated for the exercise to not only help Texans in need but also to conduct a real-world training event in preparation for any real world disasters or emergencies.
