Explore Senior Exercise Planner/MSEL Manager jobs and discover a critical, high-stakes profession at the heart of military readiness and complex organizational training. Professionals in this dual-capacity role are the architects and conductors of large-scale, realistic exercises designed to test, evaluate, and certify units for real-world operations. They operate at the strategic nexus of planning and execution, ensuring that training events achieve precise learning objectives and readiness standards. This career path is ideal for those who thrive on structured chaos, meticulous detail, and the challenge of preparing teams for high-pressure scenarios. The core of the profession splits into two interconnected domains: Exercise Planning and MSEL Management. As planners, individuals lead the end-to-end design of exercises. This involves defining core objectives, constructing detailed scenario narratives, developing evaluation criteria, and orchestrating the complex logistics of multi-agency or joint-force events. They facilitate key planning conferences, coordinate with numerous stakeholders, and ensure every exercise element aligns with overarching certification requirements. As MSEL (Master Scenario Events List) Managers, they build the script of the exercise. The MSEL is a chronological timeline of simulated events, or “injects,” that drive the scenario, challenge participants, and provide opportunities for assessment. Managing the MSEL requires crafting realistic injects, synchronizing them across all participating entities, and validating their quality and timing to create a coherent and challenging training environment. Typical responsibilities for these roles include leading exercise design teams, developing comprehensive scenario packages and briefing materials, and overseeing the integration of MSEL injects. During exercise execution, they often serve as controllers, evaluators, or senior role-players, monitoring progress and making real-time adjustments. Post-exercise, they are instrumental in conducting after-action reviews, analyzing performance data, and compiling detailed reports with corrective action plans to drive continuous improvement. To excel in Senior Exercise Planner/MSEL Manager jobs, candidates typically need a strong background in military operations, emergency management, or large-scale organizational training. A deep understanding of doctrinal standards and readiness processes is essential. Key skills include superior organizational and project management abilities, exceptional written and verbal communication for briefing senior leadership, and adeptness at complex problem-solving. Common requirements across the field often include several years of direct experience in exercise design and execution, familiarity with joint planning processes, and the ability to hold a security clearance. For strategic thinkers who want to shape preparedness and validate capabilities, Senior Exercise Planner/MSEL Manager jobs offer a uniquely impactful and dynamic career.
