Introducing project “Military Insignia”, featuring top quality military heraldry designs. Here you will find designer apparel, accessories, custom postage and gifts decorated with insignia of the United States Navy SEALs. The United States Navy SEa, Air and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's principal special operations force and is a part of the Naval Special Warfare Command (NSWC) as well as the maritime component of the United States Special Operations Command (USSOCOM). The unit's acronym ("SEAL") is derived from their capacity to operate at sea, in the air, and on land – but it is their ability to work underwater that separates SEALs from most other military units in the world. The experience gained from operating in the ocean and freshwater battlefields has shaped their identity and, as a result, they are regarded as being amongst the most highly skilled and trained amphibious units in the world. Navy SEALs are trained and have been deployed in a wide variety of missions, including direct action and special reconnaissance operations, unconventional warfare, foreign internal defence, hostage rescue, counter-terrorism, and other missions. Without exception, all SEALs are male members of either the United States Navy or the United States Marine Corps.
