Expert Infantryman Badge

The Expert Infantryman Badge (EIB) is a special skills badge of the United States Army.

The EIB was created with the CIB by executive order in November 1943 during World War II. Currently, it is awarded to U.S. Army personnel who hold infantry or Special Forces military occupational specialties with the exception of soldiers with the occupational specialty of Special Forces Medical Sergeant (18D). To be awarded the EIB, the soldier must complete a number of prerequisites and pass a battery of graded tests on basic infantry skills.

In 2017, talks about a similar badge were being discussed for soldiers without the occupation of infantry, medical, or Special Forces were put on the table and in 2019 the army established the Expert Soldier Badge for soldiers who do not qualify for either the EIB or EFMB.

The EIB is a silver and enamel badge, consisting of a 3-inch-wide (76 mm) rectangular bar with an infantry-blue field upon which is superimposed a Springfield Arsenal Musket, Model 1795. Although similar in name and appearance to the Combat Infantryman Badge (CIB), it is a completely different award. While the CIB is awarded to infantry soldiers for participation in ground combat, the EIB is presented for completion of a course of testing designed to demonstrate proficiency in infantry skills.

As of 2025, personnel who have been awarded both the EIB (or any "expert" badge) and the CIB are authorized to wear the Master Combat Infantryman Badge; otherwise, the CIB and EIB may not be worn together.
