The Coram native, a Marine who did two tours in Iraq, is the only U.S. boxer scheduled to fight Tuesday.

Herring, the captain of Team USA boxing, wears his Marine colors with pride.

"This [Marine] flag has traveled with me all over the world for the past few years and now it's here with me in London," Herring posted on his Twitter account Monday.

A 2012 national champion and two-time Armed Forces champ, Herring is the first Marine to make the Olympic boxing team since Sergio Reyes in 1992.

Other notable Marines to make past Olympic boxing teams were Ken Norton and Leon Spinks.
