Strength in Brotherhood: Two Real-Life Brothers Honor the MMA Legacy

Missouri Military Academy (MMA) has long been a place where leadership is passed from one generation of alumni brotherhood to the next. For real-life brothers Bradley Thumbi ’24 and Ethan Gachuhi ’29, that tradition takes on extra meaning. Feature photo above, then-cadet battalion commander Thumbi leads the MMA Corps of Cadets to Final Formation on commencement day, May 18, 2024.

As Thumbi rose through the ranks to become battalion commander and was accepted into the United States Naval Academy Preparatory School, his leadership set an example for Gachuhi, who joined the Academy in 2023. Inspired by his brother's journey, Gachuhi saw firsthand what it takes to lead and was motivated to follow in his footsteps. Together, they exemplify MMA’s commitment to leadership and the strength of brotherhood.

Bradley Thumbi: A Legacy of Leadership and Service 

As a distinguished recent graduate, Thumbi has set a powerful example of perseverance and leadership. Now attending the United States Naval Academy Preparatory School, he attributes much of his success to MMA’s unwavering support system.

“MMA prepared me by providing assistance from all departments — from counselors to coaches to the military aspect of life,” Thumbi says.

As battalion commander of the 135th Corps of Cadets, Thumbi embodied MMA’s core values of honor, discipline and duty. As a senior, he earned a prestigious $180,000 NROTC scholarship, a stepping stone toward his dream of serving in leadership roles, potentially even at the White House within the next decade. 

One of Thumbi's most cherished memories is deeply tied to the spirit of camaraderie he found at MMA: “My favorite memory is seeing all of us graduate together,” he says. “Those friendships stay with you.”

Thumbi's father, Fred Thumbi, is proud of his growth. “MMA helped Bradley develop strong work ethics and accountability for his actions,” Fred Thumbi says. “Personally, he became more confident and respectful to everyone around him. He is empathetic and always wants to help others."

Thumbi's advice to current cadets is simple: “Stick to the plan," he says. "Sometimes things don’t work out the way you want, but seek help and keep moving forward.”

Ethan Gachuhi: Forging His Own Path

Inspired by Thumbi's accomplishments, Gachuhi joined MMA in seventh grade and is already making his mark as an eighth-grader. An all-state cross-country athlete, Gachuhi's journey reflects both his determination and the strong influence of his older brother.

“I saw how well my brother was doing, and my parents sent me here because they believed I could do the same,” Gachuhi says. “MMA is helping me prepare for college and giving me a great education.”

Gachuhi’s dedication has led to significant strides in athletics. After a challenging start to the cross-country season, a pivotal conversation with his coach transformed his perspective.

“At the start of the season, I almost quit, but my coach gave me a talk that changed everything," Gachuhi says. "I’m so glad I stayed because now I have medals to show my family, and I’m proud of what I’ve accomplished."

This season, Gachuhi cut more than a minute from his personal best and earned his first medal—a milestone he considers one of his proudest achievements.

“The structure and supportive staff have helped Gachuhi develop self-discipline and perseverance, which has transferred to his academics and extracurricular activities,” his father says.

The Bonds of Brotherhood

The brothers’ journey at MMA reflects not just their personal achievements but also the enduring bonds of brotherhood forged within the Academy’s walls. Together, Thumbi and Gachuhi exemplify what it means to be part of the MMA family — a family built on camaraderie, mutual support and the shared pursuit of excellence.

As they continue to chart their paths, their story serves to inspire future cadets, proving that MMA is a place where young men don’t just dream of success — they create it, together.
