Navy has already revealed these incredible helmets for the annual Army-Navy game next weekend, so it was Army’s turn to reciprocate.

The Black Knights did so in style, revealing incredible all-black uniforms for the game in Philadelphia on Saturday afternoon.

As you can see below, the Black Knights will commemorate the 100th anniversary of World War I with these awesome uniforms recognizing America’s First Division:

According to a release, this is how the “First Division” came together under then-president Woodrow Wilson:

President Woodrow Wilson promised the Allies he would send “a division” to France immediately, but the Army had no such divisions. The United States quickly ordered four infantry and three artillery regiments from the Mexican border in Texas to Hoboken, N.J., to board transports to France. That group of seven regiments joined together to officially form the “1st Expeditionary Division,” later the 1st Infantry Division, under Brigadier General William L. Sibert on June 12, 1917.  With more than 28,000 men, the “Big Red One,” as the division was later nicknamed from its shoulder sleeve insignia, was twice the size of either the allied or German divisions on the Western Front.

The annual Army-Navy game kicks off at 3 p.m. Eastern time on Saturday and can be seen on CBS.
