NBC DFW was there for a sniper competition where bad guys get shot and good guys save hostages in a locked building. Teams that do it right, are back where they started in about two minutes.
"It's a difficult situation," said Eric Mekosch of Fort Worth SWAT. "You get your heart rate up and then have to start making shots in there, pretty tough shots, but it's good to get out here and do this stuff with the rest of the SWAT teams in this area."
"The adrenaline's definitely up," said Chris Paine of Lubbock SWAT. "The nerves are up and it's the best way we can simulate real life situations."
There's a nice trophy at stake which everyone wants to win, but more importantly, the SWAT officers came to Dallas to get better.
"Anytime you can come train with other departments whether it be from your city or another state, that's always good," said Cody Custer of Ouachita Parish, Louisiana. "You learn something from everybody."
"You always revert back to your training," said Chris Paine. "So your training has to be on par with the latest standards across the nation so the best teams are here so that's where we get it from."
It's also where they test their mental and physical strength and hopefully go home with more skills and confidence.
