"Gorget patches" typically refer to a specific type of uniform insignia worn by military personnel. They are patches or pieces of fabric that are sewn onto the collars of a uniform, specifically on the gorget, which is the neck area.

Historically, gorget patches were used to denote rank or specialty within a military unit. Different designs, colors, and symbols on the patches would signify different roles or positions within the armed forces. For example, in some militaries, certain colors or shapes might indicate an individual's rank, branch of service, or specific unit.

However, it's important to note that the specifics of gorget patches can vary widely between different countries and even within different branches of a single military. Additionally, as of my last training data in September 2021, it's possible that new developments or changes have occurred in military uniform regulations. Therefore, if you are seeking the most up-to-date information, I recommend consulting official military sources or documents.
