Incorporating constructive models into a 3D game is an effective, realistic and nonlinear way to prepare warfighters for operational environment complexities. In its third development spiral, The Hybrid Irregular Warfare Network-defeat Toolkit federation, or HINT, sponsored by TRADOC G2 Intelligence Support Activity, combines an immersive 3D game-based simulation - The First Person Cultural Trainer (FPCT) - with the One Semi-Automated Force (OneSAF) and the Joint Non-kinetic Effects (JNEM) models in a hybrid model framework federation. This paper drills down on this methodology, focusing on benefits, challenges and lessons learned from integrating the OneSAF and JNEM models with the FPCT 3D game. In FPCT, the player discovers IED and insurgent networks through populace relationship building. The player wins by positively affecting the mood and cooperation level of the virtual population, thereby facilitating the collection of "golden nuggets" of information. To create this gameplay, FPCT exchanges and incorporates OneSAF data, which simulates force-on-force activity, and JNEM data, which provides well-defined civilian influences such, as mood and cooperation of a heterogeneous population in an area of operation. The player then can positively affect the JNEM-driven mood and cooperation state through culturally correct populace interaction. If populace interaction is effective, critical information golden nuggets are collected during gameplay and published back to OneSAF and JNEM to model second-and third-order effects of ongoing military stability operations. Multiple data exchanges from OneSAF, JNEM and FPCT simulate dynamically changing operational conditions. The HINT methodology for combining constructive models with a 3D game provides a platform for lessons learned and also suggests other potential ways to develop simulations in this way. FPCT won the IITSEC Serious Games Competition government category in 2011, the Innovations in Department of Defense Gaming competition at the 2011 GameTech Conference, and the NTSA Cross-Function award in 2010.
