There are likely a couple of facts that you didn't know about the Army, including the official song. You may not have even realized that they had a song. They do, and it's called "The Army Goes Rolling Along." Look it up on YouTube if you want to hear it.

Many years ago, Army Lieutenant General John MacCready wanted to find a way that his pilots could keep the sun out of their eyes while flying because it was causing headaches and nausea. He asked Bausch & Lomb to create some sort of glasses that would block the rays of the sun, and hence the company Ray-Ban was created.

Though there are still some debates about this fact, it's widely believed that the first female soldier, Deborah Sampson, who served during the Revolutionary War, disguised herself as a man and named herself Robert Shurtleff. During her service, she fought against the British. She kept up the ruse for a year. She was able to pull it off by treating her own wounds and keeping to herself. Her secret was discovered when she was injured on the battlefield and lost consciousness. Still, she was a brave woman, and she was later awarded an honorable discharge and a military pension.

Though it makes sense, a fact you likely didn't know about the Army is just how much former President George Washington had to do with the creation of this branch of the military. Washington led the measure to create a unified Continental Army way back in 1775. He also chose the dress colors that Army members continue to wear to this day.

It was during World War I that the military draft was created as part of the Selective Service Act of 1917. We were entering the war and we needed more people to fight on our side. Prior to this war, there was a draft. However, the person who was drafted had the option to hire someone to fight in their place. This new draft eliminated that possibility. Prior to the new draft, there were 121,000 members. After the war, there were 2.7 million in the Army.

According to recent numbers, there are currently over one million people serving in the U.S. Army, and that number will likely grow.

That million soldiers is made up of both active-duty soldiers and reserve soldiers in the National Guard and Army Reserve.

While there are many human soldiers in the Army and the rest of the armed forces, there are also many dogs who help to protect our nation. They're called Military Working Dogs (MWD) and they have various functions. Some are trained to attack, while others are trained to sniff out drugs. Many dogs also use their senses to find explosives. In order to stay up to date on current protocols, WMDs must train for 16 hours every month.

There have been many Hollywood entertainers, singers, and movie stars who have served in the US Army.

Other famous Army veterans include Gene Wilder, singer Elvis Presley, baseball player Jackie Robinson, illustrator Charles Schulz, musician Ice-T, and actor Mr. T.

A fact you probably didn't know about the Army is that for the first 15 years of its existence, members of the 45th Infantry Division wore a patch with a yellow swastika on a red background. This was before World War II. Back then, it was not a symbol of hate. Instead, before the Nazis used it on their uniforms, the swastika was an Indian symbol of good luck. It was worn to recognize the Native American soldiers who served in the 45 Infantry Division. Once the Nazis started using it, the swastika had a negative connotation, and the Army ditched it.

One fact you probably didn't know about the Army is just how much space and land this branch of the military covers.

While there are bases in America, many bases are in Germany, Japan, South Korea, and other countries. Currently, there are about 750 military bases around the world.

Back in its infancy, the Army had many incredible inventions to help them protect the United States. One of them was a submarine that took its first mission in 1776. The sub was called the Turtle, and it was operated by a single person operating a hand and foot crank. That first mission was to help the fleet sink the HMS Eagle, an enemy ship. However, though everything was set, the pilot, Ezra Lee, became frightened and aborted the mission. Army generals tried to use the sub for a few other missions, but ultimately, it was decommissioned.

Though casual observers may hear the term "five-star general" thrown around a lot, a fact you likely didn't know about the Army is that there were only ever five of these high-ranking generals.

Eisenhower, Douglas MacArthur, George C. Marshall, and Omar N. Bradley. The rank has not been used since Omar Bradley. The President of the United States is the only one who can give an officer this rank with Senate approval.
