As states in Hurricane Dorian's path are sending out calls for help, some of San Antonio's most skilled firefighters are answering that call.
The crews are part of an elite state team called Texas A&M Task Force 1.
Though the mission is dangerous and overwhelming, it's one they've taken on many times before. They glide through the floodwaters. They hang from the air rescuing survivors, and they sort through miles of rubble.
"Each component of the task force functions slightly different but still is headed by the Special Operations Command and the local (emergency operations center)," said Joshua Powell, a San Antonio firefighter.
Powell has been part of the San Antonio Fire Department's rescue team for 14 years and has qualified for Texas A&M Task Force 1 for 13 years.
