1 SCOPE

This performance specification defines the performance requirements of the Instrumentable-

Multiple Integrated Laser Engagement System (I-MILES) Individual Weapon System (IWS) 2 which was originally called the IWS 2010.

1.1 SYSTEM DESCRIPTION

The I-MILES IWS 2 requirement is for the replacement of the existing U.S. Army direct fire dismounted MILES devices (Basic MILES, I-MILES IWS and MILES 2000) with the laser-based Tactical Engagement Simulation System (TESS) training devices. All I-MILES IWS 2 training devices shall be interoperable with Simulated Area Weapons Effects/MILES II, MILES

2000, MILES XXI, I-MILES IWS and all legacy MILES training devices (i.e. Shoulder

Launched Munitions (SLM), Combat Vehicle System (CVS), Tactical Vehicle System (TVS), Independent Target System (ITS), Wireless ITS (WITS), Universal Controller Device (UCD) and Micro-Controller Device (MCD), etc). Interoperability is defined as being able to encode/decode MILES messages from other MILES devices and being able to communicate with the specified instrumentation systems. The I-MILES IWS will be fielded worldwide and used in all geographical areas. All I-MILES IWS 2 training devices and components will be interchangeable with the MILES 2000 IWS and I-MILES IWS training devices as an objective.

Interchangeability is defined as having the ability to swap major components (halo, vest, and

Small Arms Transmitter (SAT)) between dismounted MILES systems and still be able to operate as a system. The I-MILES IWS 2 shall not require new manpower assets, personnel requirements, or qualifications.

1.2 BACKGROUND

The family of the Basic MILES was developed in the late 1970’s using technology and designs then available. Enhancements have included player identification (PID), fratricide identification, multiple levels of kill, and vulnerability due to direction of attack. New weapons, ammunition, and weapon performance have also been accommodated.
