OPERA is a computerised wargame and simulation system. It is a tool for wargame simulation and other forms of training and simulations and operations plan evaluation and analysis. Our system provides a training environment with realistic battlefield information; maintains current status report and provides after-action review to exercise commanders and staff functions.

OPERA is not only designed to do commander/staff training but also designed to provide functionalities for operation, plan evaluation and analysis. Over 90% of battlefield environments are simulated in a realistic manner, representing all elements of combat for intangible factors (troop discipline, moral, degree of training, etc.).

OPERA provides tools for doctrine training and combat procedure proficiency, which leads to significant improvements over combat power application skills. Training using OPERA requires commanders/staff to make real-time decisions based on their appreciation of the realistic, continually changing battlefield situations presented by the system. The graphic user interface (GUI) makes inputs and outputs readily comprehensible and easily within reach. Audible alerts are generated when major events take place to avoid the training audience missing any important situations. Ample data are collected during exercise to empower a wide range of analyses. This is to provide basis for the After Action Review (AAR) activity.
