In the early years of the Republic, the United States Army experimented with a number of different artillery formations. For a time, the Artillery Branch and Engineer Branch were combined. Unit designations did not yet contain the terms "Field Artillery" or "Coast Artillery," although units so designated, as well those of the air defense artillery, would eventually trace their lineage and honors to some of the early formations.
