Modeling and simulation are leading the assault of new learning technologies that are winning favor with the U.S. military. Surely the past decade has seen a proliferation of low-cost training systems throughout the military. No longer just a device for pilots, a wide range of inexpensive simulators is being used to train everyone from artillery troops to the private sector. This collaborative effort between the public and private sectors is developing standards, tools, and learning-content software for future Web-based learning. ADL's SCORM has become the standard for granularity and reusability of content. It has recently released a draft of the SCORM Version 1.3, an application profile that introduces the IMS Simple Sequencing Specification and other standardization improvements. Other companies are offering commercial versions of the nonpropnetary learning technology. L3's MMS program manager Brian Gritte says additional mentoring systems currently under development should promote greater adoption of the learning tool within the military.
