Dr. Collier earned a bachelor of science degree in physics in 1964 from Arkansas State College, a master of science degree (1967) and a Ph.D.(1970) in physics from the University of Arkansas. He was commissioned in the Ordinance Corps through the ROTC program and served on active duty with the U.S. Army from 1968 through 1970.

Beginning his career in Federal Civil Service in 1970, Collier continued his evaluation of nuclear effects as a scientist on the Safeguard technical staff at the Safeguard System Evaluation Agency (SAFSEA) also located at WSMR. After SAFSEA transitioned into the TRADOC Systems Analysis Activity, Dr. Collier remained with the activity and assumed positions of leadership. He held positions as chief of Command and Control Cost Effectiveness; chief of the Quality Assurance Branch; deputy division chief for Infantry Systems; and chief of the Battalion Model Development Branch.

Dr. Collier served as scientific advisor from 1977 to 1987 for the TRADOC Combined Arms Test Activity (TCATA) at Fort Hood, Texas. The TCATA designed, conducted, analyzed, and reported on field tests of proposed Organizational, Training, and Doctrinal concepts as well as new material. His duties involved the technical oversight of the test program as well as instrumentation development. Collier was promoted to the government’s Senior Executive Service in 1982. In January 1988, he returned to WSMR to assume the leadership of TRAC-WSMR, the TRADOC Analysis Command element at WSMR
