A military uniform gorget collar patch is a distinctive piece of insignia worn on the collar of a military uniform, particularly in historical contexts. Here's a breakdown of each term:

Military Uniform: This refers to the standard attire worn by members of the armed forces. Uniforms serve to identify individuals as part of a particular military service and often indicate rank, branch, and other pertinent information.

Gorget Collar: A gorget collar is a type of neck armor that was historically worn by soldiers as a form of protection. It covers the throat and part of the upper chest. In modern military uniforms, the term "gorget" often refers to a decorative piece on the collar of a dress uniform, rather than a functional piece of armor.

Patch: In a military context, a patch is a piece of fabric usually embroidered with specific symbols, insignia, or text. Patches are attached to uniforms to denote various things, including rank, unit affiliation, and special achievements.

Putting it all together, a military uniform gorget collar patch would be a specific piece of fabric or insignia that is affixed to the collar of a military uniform, likely for decorative or symbolic purposes. The design and meaning of such a patch would vary depending on the specific military and the era in question.
