A gorget and collar patches are components of military uniforms.

Gorget:

A gorget is a piece of armor that historically protected the throat. It was typically a metal or leather piece that was worn around the neck and extended down to cover the collarbone and upper chest area.

In modern military contexts, the term "gorget" is sometimes used to refer to a specific type of neck ornament or insignia worn by officers, particularly in European armed forces.

Collar Patches:

Collar patches are patches or insignias worn on the collars of a uniform, typically on the left and right sides. They often denote the wearer's rank, branch, or specific unit within a military organization.

They are important for identification and signify a person's position and responsibilities within the military hierarchy.

These patches come in various designs, colors, and shapes, and they vary significantly between different countries and branches of the military. They are a key element in the visual identification of military personnel and help to establish a sense of authority, camaraderie, and pride within a unit or organization.
