STE-LTS prototyping project is seeking advanced, capable and mature direct fire solution to replace the end of life direct fire engagement enablers and introduce indirect fire enabler into the Live training environment. The solutions must integrate with current live training system architecture to include Live Training Engagement Composition (LTEC), the range communication systems and the Common Training Instrumentation Architecture (CTIA).  The mature engagement solutions has to progress to enable a successful conversion with STE enterprise architecture and its associated systems (e.g. TSMT, OWT, IVAS).  The Force on Force (FoF) engagement systems will adhere to modular open system approach concepts in the design, development and sustainment activities
