The D-TaPS turns 180 degrees to present each side of a target for teaching threat/no-threat identification. Targets present themselves in two-tenths of a second. This means that trainees are not able to anticipate the target face which will be presented. Each unit can be independently controlled for tactical multiple-threat scenarios or single threat-in-a-crowd training. Placing trainees in an environment where threats have to be identified before they are engaged increases reaction time and decreases accidents in the field.
