Basic Officer Course
REFIT WEEK
“Leadership Panels ”
Week 23 at The Basic School (TBS) is packed with action and growth. Marines gear up with I-TESS for realistic combat training and dive into leadership lessons, including an inspiring talk from Gen. Mattis. They wrap up the week with mentorship from their Company Commanders and a tough 15-mile hike to build strength and teamwork.
Issue of I-TESS Gear for MOUT Training
Week 23 begins with the distribution of the Instrumented-Tactical Engagement Simulation System (I-TESS) gear to the Marines. I-TESS is an advanced, laser-based simulation system designed to provide realistic combat training through force-on-force exercises. This technology uses laser transmitters and sensors mounted on weapons and personnel, mimicking live-fire situations without the use of actual ammunition. This capability allows Marines to conduct tactical maneuvers and engage in simulated firefights, providing a realistic and safe environment to apply their training in combat scenarios. I-TESS offers real-time feedback on accuracy and engagement, allowing immediate assessment of hits and misses. After-action reviews (AARs) benefit greatly from this feedback, as Marines and their leaders can analyze performance, identify tactical errors, and improve future actions.
This gear will be critical for the upcoming Military Operations on Urbanized Terrain (MOUT) training. MOUT involves complex tactical exercises in urban settings, where Marines will practice engaging and maneuvering through buildings, streets, and alleys. By using I-TESS, Marines can simulate the dynamics of urban combat, allowing them to practice strategies such as close-quarter battle (CQB), room clearing, and maintaining communication under fire—all while safely engaging in simulated combat.
Leadership Classes from HQMC and TBS Commanding Officer
In addition to tactical training, Week 23 places a significant focus on leadership development. Marines will participate in a series of leadership classes conducted by senior representatives from Headquarters Marine Corps (HQMC) and the TBS Commanding Officer. These sessions cover essential aspects of Marine Corps leadership, ethical decision-making, and the demands of command. The classes aim to reinforce the Marine Corps’ core values of honor, courage, and commitment, encouraging Marines to reflect on their role as leaders both on and off the battlefield.
A highlight of the week will be a guest lecture by Gen. Mattis, who will share personal insights from his career on the importance of ethical and effective leadership in military operations. Gen. Mattis’ discussions often emphasize the significance of decisiveness, accountability, and humility in leadership, making his insights invaluable for the Marines as they prepare for their future roles as leaders. Topics will also include real-world case studies, ethical challenges encountered in combat, and strategies for maintaining unit cohesion and morale under high-stress conditions.
Company Commanders’ Time
The week will conclude with dedicated time with the Company Commanders. This is an opportunity for Marines to take a step back from their rigorous training schedule and refocus both mentally and physically. Company Commanders’ Time is structured to allow Marines to ask questions, review any challenges they faced during the week, and receive guidance directly from their company leadership. This session encourages Marines to reflect on their progress and seek mentorship on areas where they wish to improve. It’s also a time for company commanders to offer encouragement and advice, helping Marines maintain resilience and motivation as they move forward in training.
Throughout Week 23, your Marine is engaged in a comprehensive blend of advanced tactical simulation exercises, meaningful leadership training, and a brief period of reflection and recharge. Each aspect of this week is designed to ensure they are physically and mentally prepared for the demands of combat and leadership. Stay tuned for more updates as your Marine continues through this transformative journey at TBS.

Getting Their Steps In
Marines will wrap up the week with a challenging 15-mile hike, carrying a full combat load. This exercise is designed to test their endurance, strength, and mental resilience while simulating the physical demands of sustained operations in the field. The hike not only reinforces the importance of physical fitness but also emphasizes teamwork and the ability to perform under strenuous conditions, ensuring Marines are prepared for real-world combat scenarios.
Semper Fidelis,
