# Synthetic Training Environment **Domain:** Military training / Simulation **Doc Type:** Developed Program Node **Maturity:** Developing **Collection:** [[collections/Gamification|Gamification Collection]] ## Definition The **Synthetic Training Environment (STE)** is the U.S. Army's effort to create a converged, data-driven training environment linking live, virtual, constructive, and gaming capabilities across locations and echelons. ## Significance STE extends the lineage from [[wiki/SIMNET|SIMNET]] toward persistent, scalable rehearsal built from shared terrain, data, standards, and interfaces. It exemplifies arena-building as an institutional capability: the training world is maintained, updated, distributed, and connected to operational learning rather than treated as a single device. ## Routes [[wiki/Common Virtual Environment|Common Virtual Environment]] · [[wiki/Distributed Interactive Simulation|Distributed Interactive Simulation]] · [[wiki/Digital Twin|Digital Twin]] · [[wiki/Arena-Building Capacity|Arena-Building Capacity]] ## Sources - [[articles/gamification/America Loves Games and the Home Court Advantage|America Loves Games and the Home Court Advantage]] - [U.S. Army PEO STRI, Synthetic Training Environment](https://www.peostri.army.mil/)
