This is our final report on the Audit of the Procurement of the Combined Arms Training-Integrated Evaluation System (CATIES). We made the audit from January through September 1989 in response to a Hotline complaint alleging irregularities in the procurement of CATIES. The audit objectives were to determine whether the procedures used to acquire CATIES were in accordance with the Federal Acquisition Regulation and to evaluate whether internal controls were in place for this procurement.
