Video footage captured during the funeral procession for ‘American Sniper’, Chris Kyle. His funeral procession spanned 200 miles from Midlothian to Austin.

Kyle was a Navy SEAL sniper who served four tours in the Iraq War and had 160 confirmed kills.

He received a Silver Star, three Bronze Star Medals with "V" devices for valor, two Navy and Marine Corps Achievement Medals with "V" device, along with numerous other unit and personal accolades.

On February 2, 2013, Chris Kyle and his friend Chad Littlefield were tragically shot dead at a Texas shooting range by Eddie Ray Routh.

Routh, like Kyle, was an Iraq war veteran suffering from severe Post-Traumatic Stress Disorder.

Kyle agreed to become the young veteran's mentor, and for their first meeting, decided to take him to a local gun range.

But on the way there, Kyle and Littlefield realized just how troubled Routh was. "This dude is straight up nuts," Kyle texted Littlefield as they drove in silence. "He's right behind me," Littlefield responded. "Watch my six."

Moments after pulling into the range, Routh grabbed two pistols and fired a barrage of bullets into both men, killing them instantly.

Routh was found guilty and sentenced to life in prison with no possibility of parole.
