the AGES/ADII (Air-to-Ground Engagement System/Air Defense II) program for the US Army, outfitting a number of helicopters with training systems and producing laser simulators for the HGSS/GVLLD (Hellfire Ground Support System Simulator/Ground-based Vehicle Laser Locator Designator). Simulaser also produced the early low rate of production run of MITS (Multiple Independent Target System) and in 1989 won a development contract from the US Army for STOM (Shoot-through Obscuration Miles) that utilized long-wavelength lasers instead of semiconductor lasers in order to penetrate battlefield obscurants. Late in 1989, Simulaser was awarded a $35 million production contract for standard MILES gear, subsequently increased to $44 million, following which Loral Electro-Optical Systems, Inc., acquired the business of Simulaser from ASEC in October 1989, after which Simulaser ceased to exist. Later versions Versions made after 1986 used a loud tone to signal when a soldier was "killed". In order to turn off the noise, the soldier had to remove a yellow key from the laser module on his rifle and insert it into the box on his harness. By removing the key from the laser, the weapon could no longer score hits using the MILES system. With some systems the hit soldier is required to lie on his back to stop the noise and signal others that he is "dead". MILES 2 was released in 1991–92, and the SAWE (simulated area weapons effects) add-on was first fielded in 1992 using GPS and RF messages so that vehicles and individual soldiers can be killed from a central location due to artillery strikes, or nuclear, biological, and chemical weapons strikes. Implementation in the Summer and Fall of 1992 was at Hohenfels, Germany at the Combat Maneuver Training Center. In 1993, the range at Fort Polk was installed and tested. At the time, there were plans to add SAWE at the NTC at Fort Irwin, although instead this was implemented by using SAWE-like features via the DCI radio network. This was superseded in aircraft by the implementation of the SMODIM or the smart onboard data interface module instrumented in 1998 at all three Combat Training Centers (NTC, JRTC, and JMRC). As of July 2006, the latest version of MILES was MILES XXI, provided by Lockheed Martin. As of July 2012, the latest version of soldier worn MILES in the US is MILES IWS2, provided by Cubic Corporation. As of 2012 the most current version of fully fielded vehicle platform
