• The US Naval Education and Training Command (NETC) established an Integrated Learning Environment to help launch, track and manage almost 4000 E-Learning courses for approximately 1.2 million active-duty Sailors, Marines, Department of the Navy civilians, Reservists, retirees and family members enrolled in the Defense Enrollment Eligibility Reporting System (DEERS).
• The authors report that a "key component of this transformation" is the use of the Delta3D engine.This project, also developed through NETC, is a game engine that was harnessed to provide contextual learning and integrated assessment capabilities.
• The industry/government SCORM Run-Time Environment (RTE) specification calls for initiation of learning content, communication between content and an LMS, data transfer, and error handling. The RTE was a server application designed to work with web pages and couldn't communicate with game running on a client machine. However, a method was designed whereby the game engine running a Delta3D simulation running on a client machine could communicate to a webserver.
• The key element in the report's description is how assessment is integrated with the game: "The simulation raises simulation events as the user interacts with it. The assessment module listens to these simulation events, and uses them to track a learner’s progress toward completion of defined tasks. An assessment data model is used to combine events and tasks in a hierarchical manner to form more complex tasks, which ultimately culminate in one or more objectives. As a learner completes the training objectives, the assessment component communicates this information to the LMS."

The LMS component referred to in this work is Moodle.
