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.
Personnel who have been awarded both the EIB and the CIB are not authorized to wear both badges simultaneously. In such cases, Army Regulations allow the recipient to choose which badge is worn. A similar badge exists for medical personnel, known as the
Expert Field Medical Badge (EFMB). 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

Lane or station testing in individual tasks, graded as pass/fail ("GO"/"NO GO"). There are approximately 30–35 stations in this phase. Candidates must pass every station; if they receive a "NO GO" on their first attempt, they have one chance to retest. A second "NO GO" at any station results in a failure for the entire testing phase. Generally there are multiple stations in all the following areas (''less common/defunct tasks in italics''):
* First Aid
* Chemical, Biological, Radiological, Nuclear (CBRN) procedures
* Call for Fire (

Terminology and ritual
While training in basic skills is a major goal of the EIB program, the EIB institution additionally provides an area of common experience and vocabulary across the infantry in the US Army. This test comes around about once every 2 years to most Infantry units. Those who fail could wait over a year before they have the opportunity to try again. Most likely they will transfer or PCS to another Infantry unit that may or may not be testing that year. Thus, the wait to retest could be longer.
Sociologically, the testing phase especially acts as a rite of passage for many infantrymen. The period of testing usually stretches over several days, with the number of candidates remaining steadily dwindling and pressure similarly increasing. Traditionally, hand grenades (where the candidate has five grenades to hit three different targets) and call for fire are considered the most difficult tests.
There is a specific slang vocabulary associated with EIB testing. Graders at each station usually have EIBs themselves; a ''badge protector'' is therefore a particularly difficult grader, perceived to be protecting the status of the award which he holds. Graders typically carry a blue pen to mark "GO"s and a red pen to mark "NO GO"s; to complete the entire phase without a single NO GO is therefore to go ''true blue''. Similarly, if a candidate has one "NO GO” he is said to be ''blade running''; any mistake will eliminate him. Usually if the candidate makes a mistake and time has not run out, the grader will tell the candidate "you still have time remaining", which is a clue that the candidate may have done something wrong. On occasion, the grader will do this to unnerve the candidate even though everything is correct, which completes the rite of passage.
Master Infantryman Badge
In late 2024 it was reported that "master combat badges" would debut in Spring 2025; the Master Infantryman Badge, Master Medical Badge, and Master Soldier Badge. The badges would represent those who have earned both a combat badge ( CIB, CMB, or CAB) and an expert badge (EIB, EFMB, or ESB). The proposed "master badges" are alleged to appear identical to their respective combat badges, replacing the silver wreaths on the full-color metal badges with gold wreaths; subdued pin-on badges and sew-on badges would see their black wreaths also replaced with gold. Soldiers that had earned a combat badge but a "separate" expert badge (a CIB and an EFMB, for example) would wear the master badge aligning with their combat badge (in the case of a CIB and an EFMB, the awardee would wear the Master Infantryman Badge). As of , no official announcement has been made concerning the badges.
