What types of medals are typically worn on formal dress uniforms?

In formal dress uniforms, miniature medals are typically worn to provide a refined and distinguished appearance. Miniature medals are scaled-down versions of the full-size medals and are often preferred in formal settings because they create a cleaner look when worn on the uniform. They allow for the display of honors and recognitions without overwhelming the uniform's design, maintaining the proper military decorum.

While full-size medals are worn during ceremonial occasions, the standard for everyday or formal appearances is to wear the miniature versions. Ribbons are also worn, but in this context, they do not fulfill the requirement for medals. Decals and pins are not a standard part of the medal display in formal dress; their status is more casual or specific to certain events or units. Therefore, miniature medals are the appropriate choice for this question regarding formal dress uniforms.
