Midshipmen always find a way to incorporate the sitting president into the game.
In 2005, they carried a life-sized cardboard cut-out of George W. Bush with them into the stadium.
Cadets and midshipmen usually bring signs with them to the game, which they use to taunt their rivals.
In 2016, cadets used a catchphrase of then president-elect Trump, who was in attendance, to taunt midshipmen.
Trump will attend Saturday's game for the first time as sitting president, and will officiate the coin toss, according to the Associated Press.
The cadets and midshipmen have to march on to the field before the game, so they have to find ways to hide any signs they may be carrying.
They have to make them small enough to carry, make them out of material they can roll up or fold, or tape them together when they get to the stands.
The George W. Bush cutout? Sources say he had a place in formation and marched on the field with the midshipmen.
The brooms are a tradition of their own, but only for classes who can say they've seen four victories over their rivals.
Midshipmen held a 14-year winning streak against Army, so classes graduating in 2006 through 2016 can claim they beat Army all four years they attended.
Maybe someday Army can say they've had a decade-long streak. Until then, they'll have to get creative with their taunts
In yet another tradition, soldiers and sailors around the globe create "spirit spot" videos supporting their team.
Sailors from Littoral Combat Ship Squadron One recommend "Go Navy, Beat Army" spray to make Army fans go away.
Soldiers from the 10th Mountain Division fired a salute for Army cadets before the 119th Army-Navy game on December 8, 2018.
The anticipated "prisoner exchange."
Every year, juniors at the academies have the opportunity to spend a semester embedded with their rivals.
The midshipmen and cadets reunite with their own at the Army-Navy game, when the schools conduct a "prisoner exchange."
"Prisoners" are marched to the center of the field behind their "captors" before sprinting to re-join their classmates.
The prisoners traditionally use tape or signs in yet another taunt to their rivals.
While on exchange, midshipmen and cadets are not actually treated like prisoners, though they do face some teasing.
Cadets call their midshipmen counterparts "squids" or "middies," which midshipmen hate.
Midshipmen refer to cadets as "whoops," a reference to the monkeys in The Wizard of Oz. It's said that the costumes worn by the wicked witch's flying stooges were designed after the uniforms worn by cadets at West Point.
