McAleer said she attended her first meeting and was inducted into the committee in mid-March, but had to keep quiet about the appointment until the formal announcement on Monday.
The committee was first established in 1951, and can have up to 20 members, both men and women.
It provides the Defense secretary with advice and recommendations on such matters as attracting, treating, integrating and keeping women in the military.
"It's an exciting time and it's a pivotal time," said McAleer, referring to the fact there are more women than ever serving in the military. Integrating them into combat roles and addressing the issue of sexual assault are two important issues, she said.
Committee members meet four times yearly, visit military installations for research and also serve on committees all as unpaid volunteers.
In the Army, McAleer was stationed in Wurzburg, Germany, and served as a platoon leader, company executive officer and deputy public affairs officer with various units. She left in 1991 and was in the business world before came to Utah in 2000 with the hope of becoming an Olympian. A bobsled driver, she missed the 2002 Olympic team by two spots.
She is the former executive director of the People's Health Clinic in Summit County and wrote the book, Porcelain on Steel, Women of West Point's Long Gray Line.
