Sam Elliott will narrate veteran-made docuseries about The Old Guard

Oscar-nominated Sam Elliott will narrate the four-part docuseries Honor Guard, which follows U.S. Army soldiers throughout the grueling training required to serve at the 3rd Infantry Regiment. Also known as The Old Guard, the 3rd Infantry Regiment is perhaps best known for hosting the Sentinels who guard the Tomb of the Unknown Soldier.

Honor Guard is the follow-up to Time to Kill Productions' award-winning 2016 feature documentary The Unknowns, which follows the training of the Sentinels. Creators Neal Schrodetzki and Ethan Morse, who served together as guards at the Tomb, will now follow the intense training cycles that prepare soldiers for The Regiment, the Honor Guard Caisson Platoon, the U.S. Army Drill Team, or a Full-Honors funeral ceremony at Arlington National Cemetery.

Morse and Schrodetzki have exclusive access provided by the United States Army to capture these never-before documented training cycles. Their mission is the same as Sam Elliott's, and the reason he agreed to join the project: to honor the fallen.

Elliott's contributions to military story-telling helped inspired Morse to serve in the first place. "I first became interested in the military after seeing Sam Elliott as the Union Cavalry General John Buford in Gettysburg. Fast forward a few years and I'm serving in the California Army National Guard, just like Mr. Elliott did."

Elliott has a distinguished and longstanding reputation with the military community, due in part to the iconic roles he has played in films like We Were Soldiers and Once an Eagle.

Plus, his voice is smooth as molasses. You just know it is.
