Lieutenant General Charles D. Costanza has spent more than three decades serving in the U.S. Army, taking on some of the military’s most demanding leadership positions. His career has included command of the 3rd Infantry Division and, later, V Corps in Europe.
Away from those responsibilities, Costanza and his wife, Megan Costanza, have built a family that includes two daughters, Claire and Emma.
Because the Costanzas are a high-ranking military family, relatively little personal information about their children has been made public. Their daughters have occasionally been acknowledged at major military ceremonies, but they have largely remained outside the spotlight.

Two Daughters
Charles and Megan Costanza have two daughters, Claire and Emma.
The family has generally maintained a low public profile, and there is limited reliable information about the daughters’ ages, education or personal careers.
That privacy is particularly understandable given their father’s senior position in the U.S. military. Unlike their father, Claire and Emma have not pursued public careers that would require regular media exposure.
Their appearances at military events have primarily occurred in connection with important milestones in Charles Costanza’s Army career.
A Military Family
Growing up in a senior Army family can involve a very different lifestyle from that of a typical household.
Military assignments can require families to move between installations and, in some cases, spend periods living overseas. Command responsibilities can also place significant demands on senior officers and their families.
For Claire and Emma, their father’s career has included assignments at major Army installations as well as leadership responsibilities connected to U.S. operations in Europe.
Their family life has therefore unfolded alongside a long-running military career.
3rd Infantry Division
One of the most important chapters in Costanza’s career came when he commanded the 3rd Infantry Division at Fort Stewart, Georgia.
He assumed command of the division in 2021 and led the formation until 2023.
The 3rd Infantry Division, also known as the “Marne Division,” is one of the U.S. Army’s historic combat formations. Its headquarters is at Fort Stewart, where thousands of soldiers and their families form a large military community.
During Costanza’s tenure, his family was occasionally visible at official ceremonies and community events.
Emma’s Public Appearance
Emma Costanza received particular attention during her father’s 2023 change-of-command ceremony at Fort Stewart.
At the ceremony marking the conclusion of Charles Costanza’s command of the 3rd Infantry Division, Emma participated in the formal proceedings.
She was presented with a bouquet of red roses as part of the event, providing one of the clearest public glimpses of the Costanza family during her father’s military career.
The appearance was ceremonial rather than a sign that Emma maintains a public profile.
It remains one of the few occasions on which one of the Costanza daughters has been specifically mentioned in official Army coverage.
Claire’s Privacy
Claire Costanza has maintained an even lower public profile.
Although she is identified as one of Charles and Megan Costanza’s two daughters, detailed biographical information about her has not been widely published by official military sources.
There is no reason to assume that the lack of information reflects anything unusual. Many military families deliberately keep their children’s personal lives separate from the public responsibilities of a senior officer.
As a result, claims about Claire’s education, career or personal interests should be treated cautiously unless supported by reliable sources.
Their Mother Megan
Charles’ wife, Megan Costanza, has also played an important role in the family’s military life.
While she keeps much of her personal life private, Megan has participated in military-community activities, particularly during the family’s time at Fort Stewart.
She has been involved with family-support programs and volunteer initiatives and was publicly associated with the USO at Fort Stewart.
Her involvement highlights another side of life in a senior military family: supporting the wider community surrounding the installation.
V Corps
After completing his assignment with the 3rd Infantry Division, Costanza moved into another major leadership role.
On April 8, 2024, he assumed command of V Corps during a ceremony in Poznan, Poland.
V Corps plays a major role in U.S. Army operations and cooperation with NATO allies in Europe. Its responsibilities include strengthening readiness and coordination with partner nations, particularly along NATO’s eastern flank.
The appointment represented another significant chapter in Costanza’s military career and another international assignment for his family.
Life in Europe
Costanza’s V Corps command brought his professional life closer to NATO’s eastern flank.
The corps has a forward headquarters in Poznan, Poland, and works closely with allied and partner forces throughout Europe.
For a military family, an overseas command can bring a different set of challenges and opportunities. Relocation, changes in schools and adapting to another country can all become part of family life.
However, the Costanzas have not publicly shared extensive details about how Claire and Emma experienced the move.
Keeping Family Private
The limited information available about Claire and Emma reflects a broader pattern within the Costanza family.
Charles’ professional life is heavily documented because of his position as a senior Army officer. His command appointments, military awards and official responsibilities are routinely covered by the Army.
His daughters, however, are private citizens.
Their occasional appearances at military ceremonies do not make their personal lives public property. There is consequently little verified information about their day-to-day lives, education or future careers.
Their Father’s Career
Charles Costanza’s military career has included command at multiple levels.
He graduated from the U.S. Military Academy at West Point and was commissioned into the Army in 1991. Over the following decades, he served in operational assignments and senior leadership positions, including deployments and assignments involving Iraq, Bosnia and Europe.
His career eventually led to command of the 3rd Infantry Division and V Corps.
For Claire and Emma, those achievements have been part of their family story, even though they have generally remained behind the scenes.
Charles Costanza and his wife, Megan, have two daughters: Claire and Emma.
Both have maintained a largely private life, with only limited information about them appearing in official military coverage.
Emma received public recognition during her father’s 2023 change-of-command ceremony at Fort Stewart, while Claire has remained even further removed from the public spotlight.
Their father’s career has taken the family through major Army assignments, including his command of the 3rd Infantry Division and his assumption of leadership of V Corps in Poland in April 2024.
For readers searching for Charles Costanza’s children, the essential information is therefore straightforward: he and Megan are parents to Claire and Emma, but detailed personal information about the daughters has not been broadly disclosed.
That distinction matters when discussing the family of a senior military leader. Charles’ professional record is a matter of public interest, while his daughters have largely been able to maintain the privacy that comes with living outside the military spotlight.
