The Army is the oldest branch of the military, established back in 1775.

It's also the largest branch of the military with more than 700,000 soldiers.

Those are just some of the things that convinced Treamon Lacy to join years ago.

Kasandra Ortiz has more on his heroic story on how he served his country.

When you walk into the Georgia VECTR Center in Warner Robins, volunteer Treamon Lacy is a welcoming face.

The center is an education and transition center for veterans.

"There's some things I experienced as a veteran and I was thinking I could help other veterans," said Lacy, and along with his background as a veteran, he uses more than 10 years of Army experience to encourage others.

You might even say Lacy was destined to serve.

"My dad, he's been in the Air Force for 25 years, so the military's always been kind of instilled in my family. My grandfather was in the military -- he was in the Army," Lacy said.

When Lacy was 17 years old, he signed up for the Army.

By January 2005, he started his first tour to Camp Taji in Iraq with the 10th Transportation Battalion.

Lacy says deployment gave him a new appreciation for what he had back in the United States.

"I'm happy to be able to just walk down the street or drive to the store or wear the clothes I want to wear. You know, to just have an opportunity. All those things helped me to not take anything for granted and try to live your life the best way you can," said Lacy.

Lacy deployed for a second time in 2008 for a year in Balad, Iraq.

5 years later, he medically retired for a back injury, but says serving in the Army was a humbling journey.

"I'm proud of my service because I feel like I was part of a goal, and that's to keep America safe. I'm glad I was able to do my duty and serve my country," said Lacy.

It's a heroic sacrifice to protect the Land of the Free.

In addition to volunteering to help other veterans, Lacy is currently studying engineering technology at Central Georgia Technical College and at Middle Georgia State.
