 My name is Sergeant First Class Sergio Castillo. I'm First Platoon's platoon sergeant in Bulldog Company, 1st and 5th of 2nd Infantry Regiment, 101st Airborne Division Air Salt. I decided to join the Army, joined in late or 25 years old. I wanted the adventure. I wanted to see the world and I wanted to possess skills that the civilian world does not. A lot of my friends that went to Fallujah, fight in Iraq, came back with the good experiences and I wanted to be a part of that. I wanted to serve the country that's given me the freedom. I was born in Mexico so I am a naturalized citizen and I wanted to return that favor. What drives me to continue to serve, I've been in for 11 years now, my soldiers. They motivate me. I like teaching and when I teach and they learn and execute that's the most rewarding as an NCO is seeing your soldiers learn and grow. Coaching team leaders and squad leaders and watching them develop and grow, that's what drives me to keep forward. To continue my service, not only that, it's my family too. My wife and my kids, they're well taken care of and this is a lifestyle. It's not a job, this is a career. So my family is taken care of and my job is satisfying and rewarding everything that we put hard work into and you see it execution and then you see them develop and grow. It's the most rewarding thing for an NCO to see.
