A former Army captain and father of two is fighting for his life after being struck by a boat propeller while snorkeling in the Bahamas during a family vacation.

On June 30, Brent Slough of Prosper, Texas, was snorkeling in the crystal clear water near the shores of Exuma when “this boat came out of nowhere — and never stopped,” his wife, Whitney Slough, told Dallas outlet WFAA.

“They know they hit him. They saw him snorkeling,” she said. “And they drove off.”

“We’re lucky that he’s alive,” Whitney told the outlet. “And there’s no way that they should be able to get away with this.”

In an update Sunday, Whitney wrote on Facebook that Brent was moved to an intermediate ICU. 

“A step in the right direction. Praise God,” she wrote. “Please keep the prayers coming!”

Brent was an infantryman in the regular Army from May 2005 to April 2011, an Army spokesperson confirmed to Fox News Digital.

He deployed to Iraq from May 2007 to July 2008 and was a captain when he left. 

His awards include the Bronze Star Medal, Army Achievement Medal, National Defense Service Medal, Iraq Campaign Medal with campaign star, Global War on Terrorism Service Medal, Army Service Ribbon, Overseas Service Ribbon, Ranger Tab, Expert Infantryman Badge, Air Assault Badge, and Parachutist Badge.
