When it comes to the backbone of the U.S. Army, few positions are as vital, challenging, and respected as the 11B MOS (Military Occupational Specialty), also known as the Infantryman. For recruits considering enlisting in this role, it represents an opportunity to experience the essence of teamwork, courage, and service to the nation. But what exactly does the 11B MOS entail, and is it the right path for you? 

This blog will break down everything you need to know about being an 11B Infantryman in the Army—from the responsibilities and training to the benefits and potential career paths. 

What Is the 11B MOS?

The 11B (pronounced 11 Bravo) MOS refers to the Infantryman, a role rooted in ground combat. Simply put, infantry soldiers are the heart of the Army's combat forces. They are trained to engage and neutralize enemy forces, often on the front lines or in environments that require grit, endurance, and resilience. 

The Infantryman is responsible for tasks such as:

• Defending the country and its interests during ground operations.
• Operating weaponry—including rifles, grenade launchers, and complex weapon systems.
• Conducting reconnaissance to gather strategic information.
• Participating in tactical maneuvers and combat scenarios.

The MOS 11B is traditionally seen as one of the Army’s most challenging but rewarding roles, requiring a blend of physical and mental toughness.

Why Choose the 11B MOS?

Becoming an Infantryman is not for everyone, but for recruits who want a career that epitomizes service and leadership, there is no better path. Here are a few key reasons why the 11B MOS could be the perfect fit:

1. Core of the Army

Infantry soldiers are often seen as the foundation of military operations. Without them, many combat strategies could never be executed. There is a deep sense of pride and tradition attached to this role.

2. Adrenaline-Fueled Job

For those who thrive in high-energy, fast-paced environments, the life of an 11B Infantryman delivers on excitement. Whether executing tactical movements or operating advanced weaponry, there is rarely a dull moment. 

3. Team-Oriented Environment

Teamwork is at the heart of every Infantry unit. An 11B MOS is all about building strong connections with your peers, knowing that you can rely on one another in any situation.

4. Leadership Opportunities

The Infantry challenges soldiers to step up and lead. Graduates of the 11B training often develop critical leadership skills that serve them both during their military career and beyond.

What to Expect During 11B Infantry Training

Before officially becoming an 11B Infantryman, you must successfully complete Basic Combat Training and Advanced Individual Training (AIT).

Here’s an overview of both phases:

1. Basic Combat Training (BCT)

Every soldier begins their Army career with Basic Combat Training, a rigorous 10-week program designed to turn civilians into soldiers. During this phase, you’ll learn:

• Physical fitness standards.
• Basic marksmanship and weapons handling.
• Teamwork and discipline.
• Army values and traditions.

2. One Station Unit Training (OSUT)

Following Basic Training, recruits enrolled in the 11B MOS proceed to One Station Unit Training. This combined program includes both AIT and Infantry-specific training tailored to the demands of the Infantryman role. Here, you’ll master:

• Complex weapon systems.
• Tactical maneuvers and patrol operations.
• Reconnaissance and surveillance.
• Survival skills, including land navigation and first aid in combat scenarios.

Training as an Infantryman is physically and mentally demanding, with a heightened focus on resilience and endurance. Expect to be pushed beyond your limits—but everything you learn will prepare you for the battlefield and beyond.

Physical Standards

Infantry recruits are held to some of the highest physical standards in the Army. You’ll need to excel in the Army Combat Fitness Test (ACFT), which measures six areas:

• Deadlift
• Standing Power Throw
• Hand-Release Push-Ups
• Sprint-Drag-Carry
• Plank
• 2-Mile Run

Meeting these physical requirements is essential to ensuring you can handle the physical challenges of the 11B MOS.

Entrance Requirements

Generally speaking, the requirements to enter the infantry are: 

• A U.S. Citizen or permanent resident with a valid Green Card
• 17 to 34 Years Old
• High School Diploma or GED
• Meet Tattoo Guidelines
• No Major Law Violations
• No Medical Concerns
• 77 ASVAB Score Combat (CO)

A Day in the Life of an 11B Infantryman

Life as an Infantry soldier is intense, rewarding, and often unpredictable. But what does a “typical” day look like for an 11B? While every mission is different, here’s what you can generally expect:

Morning Physical Training (PT)  

Infantry soldiers start their day early with PT, which includes running, weightlifting, and metabolic conditioning to ensure peak physical fitness.

Weapons Training  

Whether on the firing range or in the field, proficiency with weapons is critical in the Infantry. Soldiers regularly practice with rifles and other complex weapon systems.

Combat Drills and Tactical Maneuvers  

Teamwork doesn’t happen overnight. Infantry units frequently train by running combat drills and tactical scenarios to ensure they operate seamlessly as a unit.

Specialized Tasks  

Depending on the mission, daily tasks may include reconnaissance, constructing defensive positions, or conducting patrols in simulated or combat environments.

Advancing Your Career in the 11B MOS

While many recruits see the 11B MOS role as a stepping stone to other leadership opportunities, it can also serve as a long-term career with plenty of growth potential.

Here’s how:

Rank Advancement  

Infantry soldiers who show leadership potential can move up the ranks to become Team Leaders, Squad Leaders, or Platoon Sergeants. 

Specialized Training  

Soldiers can undergo additional training to join elite units such as the Army Rangers or Special Forces.

Transitioning to Civilian Careers  

After serving, Infantry soldiers often transition into civilian careers in areas such as law enforcement, security, or leadership roles. Employers frequently value the discipline, resilience, and teamwork skills instilled in Infantry veterans.

Challenges to Consider

Before committing to the 11B MOS, it’s essential to consider the challenges. Infantry roles are physically and mentally demanding, requiring unwavering dedication, long hours, and frequent deployments.

This role is also most suited for individuals comfortable with unpredictability—as an Infantryman, you never know where duty will take you next.

Is the 11B MOS Right for You?

Deciding to pursue the 11B MOS is not a decision to take lightly. It requires a willingness to push yourself to new limits, a drive to serve your country, and a love for teamwork. For those who thrive under pressure and crave a role with purpose, the 11B Infantryman MOS offers an unparalleled opportunity to grow personally and professionally.
