These are based on a directorate of the US Department of Defense (DoD) to the Defense Advance Research Projects Agency (DARPA) to facilitate inter operability and reuse amongst the components of simulations.

The prime driving force for development, implementations & validation is the DMSO office.

-The DIS to HLA  transition has been successful and has been demonstrated by major training exercises. It is now part of the Distributed Mission Training (DMT).

HLA has permitted high fidelity large-scale distributed man-in-the-loop simulations. HLA basic structure is founded on the concept and definitions of Federates and Federations.

HLA is the way of the present and the future in DMT. 

Though HLA is an ultra-modern State of the Art framework, it can be adapted to older simulators.There are methods and software tools to implement HLA based inter-operability in older simulation systems. Similarly DIS simulation systems can be upgraded to HLA.

Though not all aspects of HLA are exportable, its implementation within the NATO countries constitutes the most expanded implementation outside the US.

HLA  implementation is not inherently tricky, however due to its complexity, it requires in depth familiarity with it as well as with the legacy components that is to be ported with.

It is generally inconceivable for any modern army to train, plan and rehearse without integrated  HLA  capabilities.

HELLENIC SIMULATIONS has the knowledge, capabilities and experience to implement HLA into existing simulation systems and provide a comprehensive secure network of HLA compliant simulators, which are located at different military bases. 

HELLENIC SIMULATIONS offers HLA training seminars and classes to interested qualified parties in Greece.

HELLENIC SIMULATIONS can also undertake  the upgrading  of older systems and can provide compliance, validation & acceptance testing to interested parties.
