How are military insignia patches formed and modified, are an interesting story? An example of this can be witnessed in the way the Fifth Special Forces Group was formed for the Vietnam War, in 1962. The United States Special Forces, Vietnam (Provisional) was formed from members drawn from the First Group, the Fifth Group, and the Seventh Groups. The soldiers operated in small units and created several insignia patch designs for their identification. The Fifth Special Forces Group used the insignia of the beret fish that combined the yellow from the first group, red from the seventh, and black from the Fifth that was incorporated with bend lets that represented the flag of Vietnam.

Insignia are available hand-sewn and machine-sewn, as well as in several other variants. This is largely because many of the insignia for the US army personnel were remade elsewhere in different countries or within the country when new arrivals came or when new recon teams were put together.

A plethora of designs of military insignia patches has seen the emergence of several hundred private vendors who offer comprehensive solutions. These vendors offer customized solutions for the military, the police, business, uniform suppliers, teams and government agencies. They can virtually manufacture patches of any shape and size and in any color.

The military insignia was used on different items in the US. Initially, in the early years, the patches served as an insignia for the Army. This was later practiced in the Navy and the Air force used them. The Marine Corps also used patches during the Second World War but discontinued their use immediately after the war. The US Navy was never partial to shoulder sleeve insignia, and had its own traditions with respect to the use of the insignia. There were very limited cases where naval personnel wore insignia in the fashion of shoulder sleeve insignia.
