Army branch insignia is similar to the line officer and staff corps officer devices of the U.S. Navy as well as to the Navy enlisted rating badges. The Medical, Nurse, Dental, Veterinary, Medical Service, Medical Specialist, Chaplains, and Judge Advocate General's Corps are considered "special branches", while the others are "basic branches".
