In addition to the calculator, Ammunition Managers, Ammunition Specialists, and Quality Assurance Specialist Ammunition Surveillance (QASAS) personnel can practice critical, on the job skills in the built-in gaming component. The game consists of 10 challenging scenarios that will not only utilize the mobile ESQD calculator, but also leverage knowledge of Army ESQD standards.
