FragSim is designed to provide, to troops training in the field, real-world real-time indication of fatality from projected weapons: artillery, mortars, naval gunfire support, and aerial delivered weapons. It is expected the selection menu will group high explosive projectiles by calibre or bomb weight.

Status: the initial concept has been defined, and the ability of the Layer3Services WiFi system to emulate fragmentation effects is effective. Technical and scientific input for the system is being gathered. Support for the development of FragSim is invited.
