The mortar simulator combines the forward observer simulator with strap on hardware, that allows for complete mortar training. The observer sits in front of a big screen using the tools at his disposal (binoculars, laser range finder, GPS and compass) to give radio feedback to a mortar crew that can be 500 meters away.
The mortar setup uses special training rounds, that read nose fuse settings, as well as number of charges. We currently have HE, smoke and illumination rounds. When a round is dropped in a mortar, that information, together with the bearing and elevation is sent to the computer, that calculates the flight path, and displays the effect to the observer.
The instructor has full control over the simulation via a separate notebook, and can set up scenarios or modify them in real time to suite the training requirements. The whole exercise as well as all radio communication is recorded and available afterwards for debriefing.
