What type of badge is worn as the highest badge?

The Combat Infantry Badge and Expert Infantry Badge are indeed considered the highest badges worn by soldiers, worn to signify distinguished service in combat and exceptional proficiency in infantry skills, respectively. The Combat Infantry Badge is exclusively awarded to infantrymen who have engaged in ground combat, thereby highlighting their direct involvement and contribution to military operations. The Expert Infantry Badge, on the other hand, is a recognition of an individual's mastery of the infantry's skills and abilities, further signifying a soldier's dedication to excellence within their field.

Other badge types, such as the Marksmanship Badge, Achievement Badge, and Service Medal, have important representations in terms of skills and accomplishments within the military framework, but they do not carry the same level of significance in direct combat or infantry specialization as the Combat Infantry Badge and Expert Infantry Badge. Thus, these two badges are regarded as the highest badges reflecting a soldier's expertise and valor in the Army.
