After completing the rigorous challenges of Marine Corps boot camp, infantry Marines transition to the School of Infantry (SOI), a critical phase in their transformation from recruits to combat-ready warriors. Located at Camp Geiger in North Carolina for the East Coast and Camp Pendleton in California for the West Coast, SOI is where Marines refine their infantry skills and adopt the mindset required for battlefield success. This 59-day program is divided into two phases: Infantry Training Battalion (ITB) for non-infantry Marines and Infantry Skills Course (ISC) for infantry Marines, with the latter being the focus for those destined for infantry units.

The ISC phase is where infantry Marines truly specialize. Here, they master marksmanship, fieldcraft, and small-unit tactics through hands-on training and realistic scenarios. For instance, Marines spend hours on the rifle range, honing their ability to engage targets at various distances, a skill that directly translates to combat effectiveness. They also learn to navigate using maps and compasses, build fighting positions, and execute patrols—skills that are drilled into muscle memory through repetition and stress-inducing exercises. This phase is not just about physical endurance but also mental resilience, as instructors push Marines to think critically under pressure.

One of the most distinctive aspects of SOI is its emphasis on teamwork and leadership. Marines are organized into fire teams and squads, where they learn to rely on one another in high-stakes situations. For example, during live-fire exercises, each Marine must trust their teammates to provide covering fire, communicate clearly, and execute their roles flawlessly. This fosters a sense of camaraderie and accountability that becomes second nature by the end of the course. Additionally, Marines are evaluated on their leadership potential, with top performers identified for future roles as squad or team leaders.

Practical tips for Marines entering SOI include maintaining physical fitness, as the demands of the course are relentless. Arriving with a strong foundation in basic infantry skills, such as weapon maintenance and land navigation, can provide a significant advantage.
