Rob Gronkowski is retired from the NFL but he's not done giving back to his fans ... the future Hall of Famer recently surprised a retired U.S. Army veteran, wounded in combat, with an awesome, customized truck!
The G.O.A.T. tight end partnered up with USAA to deliver a 4-door truck to Specialist Jonny Flores who served four years in a field artillery unit ... where he worked as a .50 cal gunner, among other jobs.
"Today I'm helping USAA give away a recycled ride to a deserving US military veteran," Gronk said on Tuesday.
