This study aimed to design and develop a weapon simulation system using laser light to supplement the training program of the police and other anti-terrorist units in the Philippines with a technology to improve their performance. The system was comprised of sensitive light sensors, laser pointer, transmitter, and receiver. Experimental development was used to construct the device. Meanwhile, quantitative method was implemented to evaluate the functionality and reliability of the device. The evaluation was guided by the assessment sheet provided by the researchers. The average rating was computed to determine the overall result. In particular, the DCPO SWAT Team evaluated the system. The system was mounted in a standard issued Gloc9 handgun loaded with blank ammunition. For safety purposes, the target used in the live firing evaluation was a dummy. On the other hand, when using the system in simulations, the weapons used were airsoft guns. The evaluators considered the system to be an effective tool for training. Through its simulation component, it could evaluate the movements of anti-terrorist force during combat situation.
