While at the University of Illinois, he participated in the Reserve Officers' Training Corps and was commissioned a second lieutenant upon graduation. In 1966, as an officer in the Air Force Reserve, he earned his Master of Arts degree in education from Our Lady of the Lake University in San Antonio, Texas.

Ardisana worked for several U.S. military agencies including the Air Force, the NSA, and the Army Signal Corps. In March 1952 he was called to active duty to train at the Brooks Air Force Base as a student in traffic-analysis.

Upon completion of his training in August he was transferred to Washington, DC to work as a language officer for the Armed Forces Security Agency. In 1956 he was transferred to Fort Meade where he developed new analysis techniques that are still in use today. In 1958 he was transferred to Zweibrücken, Germany, where he developed an operations communications system still used by the cryptography community today. Between 1963 and 1965 he served as chief of the Operations Inspection team at Kelly Air Force Base, San Antonio, Texas.

In 1966 he became head of the Operations Systems Evaluation and Management Branch at the U.S. Air Force Security Service Directorate of Operations.

Legacy
Ardisana's expertise in cryptography allowed him to develop a number of important changes to USAF cryptologic operations and procedures. Much of his work in designing the Operations Communications remained the standard for 25 years within the US Air Force. His work was a "key concept" that allowed the development of the Critical Intelligence Communication System.
