Matrix Pro Sim
Professional wargaming and simulation brand of Slitherine Software UK, publishing COTS defense simulation titles (Command: PE, Combat Mission: PE) for military training and analysis.
Matrix Pro Sims is the professional/defense-simulation brand of Slitherine Software UK Ltd (trading jointly with Slitherine Corporation, USA, and Matrix Games LLC), operating alongside the company's commercial wargaming publishing business. Since 2015 the brand has supplied commercial-off-the-shelf (COTS) wargaming and analysis software — principally Command Professional Edition (Command PE) and Combat Mission Professional Edition — to over 150 defense organizations across 22-23 countries, including the US DoD, UK MoD, Royal Australian Air Force, NATO, and industry primes such as Lockheed Martin and BAE Systems. The company maintains a four-year analytical partnership with the UK's Defence Science and Technology Laboratory (dstl), which credited the software with halving analysis time and cost, and in August 2024 UK Strategic Command's Defence Modelling and Simulation Office (DMSO) awarded Matrix Pro Sims a one-year contract for Command PE to support the new Defence Experimentation and Wargaming Hub in Portsmouth.
