Navy just released its new uniform combination for its game vs. Air Force on Sept. 11, which marks the 20th anniversary of the 9/11 attacks.

The uniforms pay homage to the United States Marine Corps. Have a look:

According to Navy, this is the first college football uniform to “celebrate the United States Marine Corps.”

This uniform is a representation of the Marine’s “Dress Blue A” uniforms. Similar elements include white gloves, black cleats, red trim, and royal blue pants.

The Midshipmen’s new uniform also features a red stripe down the pants. Here’s what Navy says about this element of the uniform:

Famously known as the “Blood Stripe” – this element first appeared on dress blue trousers in 1798. It was rumored to represent the bloodshed of Marines during the Battle of Chapultepec in 1846, but is more modernly known as a way to honor all our fallen and injured Marines.

Navy explains the full history behind the uniform and the little details that went into it on their website.

Navy hosts Air Force on Sept. 11. The Midshipmen open their season vs. Marshall on Sept. 4.
