Special Duty Assignments

The Drill Instructor (DI) is the cornerstone of Marine Corps transformation, with the primary responsibility of training America’s future Marines through relentless discipline, tireless leadership, and uncompromising standards. As a Marine Corps Drill Instructor, you will train, mentor, and mold recruits into warriors, instilling in them the Corps' values of honor, courage, and commitment. You will create and control chaotic moments throughout recruit training so your recruits will be prepared for the actual chaos of combat.

The Drill Instructor legacy began in the crucible of American military history. Since the formal establishment of recruit training in the early 20th century, DIs have forged civilians into Marines. It is a duty steeped in tradition, sacrifice, and pride. Every cadence called and every uniform inspected reflects decades of earned respect and unwavering excellence.

Today, that mission remains as vital as ever. The world changes, but the need for elite warfighters does not. The Drill Instructor continues to be the first and most critical leader in every Marine’s journey.

From the moment recruits step onto the yellow footprints, they will look to you as the embodiment of the Marine Corps—sharp, resolute, and mission-focused. If you possess the strength to lead from the front, the endurance to never relent, and the drive to uphold the highest standards—this Special Duty Assignment could be your calling.

The Marine Security Guard (MSG) stands as the shield of American diplomacy—tasked with protecting U.S. embassies, consulates, and classified information in more than 150 countries worldwide. As an MSG, you represent the Marine Corps and the United States to the world, standing post at our nation’s most sensitive and strategically important facilities. Your mission: protect personnel, safeguard national secrets, and maintain a calm, commanding presence in times of crisis.

The Marine Security Guard program was officially established in 1949, but Marines have been guarding U.S. diplomatic missions as far back as the early 1800s. From the Cold War to the Global War on Terror, MSGs have held the line in every region of the world—often in unstable or high-threat environments. Whether it's evacuating American citizens during political unrest or standing watch during tense international standoffs, the MSG has always been a quiet professional operating in the highest levels of global importance.

Today, that role is more essential than ever. In a world defined by geopolitical complexity and digital threats, the presence of a Marine guard at a U.S. embassy is a symbol of strength, resilience, and unwavering commitment. If you have the discipline to serve independently, the poise to handle international pressure, and the pride to represent the Eagle, Globe, and Anchor on foreign soil—then Marine Security Guard duty could be your next challenge.

The Marine Corps Security Force (MCSF) is an elite group within the Marine Corps, responsible for guarding the nation’s most critical assets—nuclear weapons, strategic naval installations, and high-value infrastructure. As an MCSF Marine, you operate in highly secure, mission-critical environments where failure is not an option. Trained in advanced security operations, urban combat tactics, and anti-terrorism measures, MCSF Marines are always prepared to respond with precision and force.

The origins of the MCSF mission date back to the need for dedicated protection of naval installations and special weapons during the Cold War. Since then, the role has expanded globally to include detachments aboard warships, in classified facilities, and at high-security locations worldwide. Marines selected for MCSF duty go through specialized training at Security Forces Training Company to prepare them for fast-paced, high-threat environments where readiness is paramount.

In today’s world of evolving threats—from terrorism to cyber warfare—the Marine Corps Security Force remains a frontline defense in the protection of national interests. The mission is vital; the work, demanding but rewarding. If you are looking to operate with precision, serve with purpose, and protect what few ever see—MCSF duty could be your proving ground.

The Marine Combat Instructor (MCI) hones every Marine’s ability to fight, survive, and win. Stationed at the School of Infantry (SOI), MCIs are responsible for transforming new Marines into disciplined, combat-ready warfighters. Through hands-on instruction in weapons handling, fire and maneuver, small-unit tactics, and battlefield decision-making, MCIs ensure that Marines are ready to meet the demands of combat, anywhere in the world.

The role of the Marine Combat Instructor was formalized in the wake of post-Vietnam restructuring, as the Corps recognized the need for specialized instructors to elevate infantry training beyond basic recruit instruction. What began as a support role has evolved into a cornerstone of Marine Corps readiness. MCIs not only teach the fundamentals of warfighting through combat training—they pass down the warrior ethos and sharpen the edge of the Corps’ combat effectiveness.

Today, MCIs don’t just teach Marines how to shoot, move, and communicate—they build mental toughness, develop battlefield leaders, and reinforce the mindset that separates Marines from the rest. If you have the heart to lead by example, the skill to instruct with precision, and the grit to prepare the next generation for the fight—you are ready to take on the role of Marine Combat Instructor.

The Marine Corps Recruiter is the sharp edge of the Corps’ future—charged with identifying, mentoring, and guiding the next generation of Marines. As a recruiter, you shape the very foundation of the Marine Corps by finding individuals with the heart, discipline, and warrior spirit to earn the title Marine. You represent the Corps in your community, standing as a symbol of integrity, professionalism, and opportunity.

Recruiting duty traces its legacy back to the birth of the Corps in 1775, when word-of-mouth and local efforts built the ranks of the Continental Marines. Over time, the mission evolved into a formal and critical component of Marine Corps operations, especially in times of national conflict and peace. From post–World War recruiting drives to the all-volunteer force of today, Marine Corps Recruiters have never just “hired”—they’ve inspired.

Now more than ever, the mission demands excellence. In an age of increasing distractions and declining eligibility, it takes exceptional Marines to find exceptional people. The Marine Corps Recruiter is not just a gatekeeper but a mentor and leader who shapes lives and strengthens the Corps, one future Marine at a time. If you have the confidence to lead from the front and the drive to impact lives forever—recruiting duty is your battlefield.
