A couple of more things; traditions and cultures are vastly different. The US navy was around long before a standing army. Also there’s a notion of distance to the people pulling the triggers; point of the spear. In the navy and Air Force relatively few people pull triggers, in the army and marine nearly everyone does which leads to the old saying; the marines are a department of the navy, the men’s department.

Their missions are different to clearly. Naval operations center around force projection and protecting aircraft carriers ie aircraft carrier battle groups. The army conducts either low intensity peace keeping or counter insurgency ops or high intensity ops, like countering a soviet invasion of Western Europe during the Cold War ie maneuver and heavy army.
