Army vehicle gets stuck in Houston floodwaters - then a monster truck drives up

In a thrilling video from the aftermath of the Hurricane Harvey, a U.S. Army vehicle is shown stuck in the floodwaters. According to the videographer, people flagged down a monster truck passing by that was on a mission to help victims, and the driver helped drag the vehicle onto dry land.

Houston resident Josh James took the video and explained to ABC News that he had called up his friends at the dirt racetrack Rednecks with Paychecks in Dallas to enlist the aid of five monster trucks in helping out with the rescue efforts.

James helped coordinate a rescue team of 200 boats, 300 trucks and 600 personnel.

They began taking calls for help Saturday, a day after the hurricane hit land, and have rescued many people. The volunteers come from all over Texas and beyond, and includes the "Cajun Army," a nickname for rescue volunteers from Louisiana.

"We literally have people from all over," James said. He's also helping with his personal vehicle. "I have a lifted Jeep that can get to more places that people can't," he said. "That's what drove me out."

Hurricane Harvey has taken the lives of more than 30 people, and it's estimated to be one of the costliest disasters in U.S. history, with tens of billions already in damages.

Already 180,000 homes have been affected, damaged or destroyed by the hurricane and the ensuing floods.

"It's an amazing feeling to see how strong our community is coming together," James said.
