I find it slightly confusing that each branch of the military has distinct names for their members (like soldiers, sailors, airmen). Is there a historical or maybe even functional reason behind this? Hoping someone can shed some light on this for me.
The terminology used to refer to members of different branches of the U.S. military is rooted in both history and tradition.
The term "soldier" is derived from the Latin "solidus," a type of Roman coin, which hints at the history of paid professional armies. This term is closely associated with land-based military forces, so it naturally became the term of choice for the U.S. Army, which is primarily a land force.
"Sailor" is used for members of the U.S. Navy, stemming from the term's connection to seafaring and naval traditions. The word itself originates from the Old English "sælere", which means "seaman" or "one who sails." Given that the Navy's operations are largely sea-based, the term sailor is quite fitting.
The term "airman" used in the U.S. Air Force reflects the branch's focus on air and space operations. Introduced when the Air Force was established as a separate branch post-World War II, it was helpful in distinguishing it from the Army, from which it was originally part.
"Marines," used for members of the U.S. Marine Corps, comes from the word "marine," referring to something related to the sea. Established in the 18th century, the Marine Corps originally served as an infantry unit aboard naval vessels, hence the name.
For the U.S. Coast Guard, members are often referred to as "Coast Guardsmen". This term highlights the marine-focused, but also the multi-mission, nature of their duties spanning maritime safety, security, and stewardship.
As for the U.S. Space Force, members are known as "Guardians". This term emphasizes their role in protecting U.S. and allied interests in space.
Essentially, these different names serve to highlight the unique roles and histories of each branch of the military.
