IDF Border Guard Tag. Typically, each IDF unit (yehida) has its own shoulder tag. Shoulder tags consist of a long section and a tip, which can be one of four shapes: a circle (commands, directorates and air force units except anti-aircraft), a square (Golani Brigade), a diamond, or a shield-like shape (most common). The Israel Border Police is the military branch (gendarmerie) of the Israeli Police. It is also commonly known by its Hebrew abbreviation Magav, meaning border guard, whilst its members are colloquially known as Magavnikim. Border Guard is often used as the official name of the Israel Border Police in English.
