The retired Navy SEAL at the heart of the book and movie “Lone Survivor” has drawn cheers and shouts of “thank you” from the crowd at the Republican National Convention.

Marcus Luttrell was introduced by former Texas Gov. Rick Perry. Luttrell spoke about the need for the government to take better care of veterans when they return to the United States.

Luttrell praised Donald Trump’s commitment to the military. Luttrell also somewhat touched on the recent violence against police officers — telling delegates that the nation’s “next war is here.”

And in a reference to the Black Lives Matter movement, Luttrell said: “In order for any life to matter, we all have to matter.”
