A four-nation Combat Identification Working Group (CIWG) has conducted field trials for its International Combat Identification Interoperability program at the Munster based Bundeswehr Armour School but so-far, while system evaluation continues, it is dependent on funding priorities. An even more ambitious program to reduce individual fratricide risk is based on the so-called Joint Expeditionary Digital Information (JEDI) system. This is based on a rugged field palmtop computer, satellite phones and laser binoculars, to pinpoint precise GPS coordinates of foe and friend, and pass the information over satellite phone network to forward control HQ. This equipment, when fielded will allow tactical commanders to track their troop locations during combat, reducing fratricide risk.

One of the problems encountered during development, was the deactivation of the Iridium satellites system and its replacement with Globalstar communications, which requires new adaptation process, taking valuable time and funding, which could be critical.
