Army vs. Navy: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 21, 2023
The army is a land-based military force, while the navy operates in marine environments.

Key Differences

The army primarily operates on land, engaging in ground warfare and territorial defense. In contrast, the navy functions in maritime settings, focusing on sea-based defense and offensive operations.
Army personnel are trained in various ground combat roles, from infantry to armored warfare. Conversely, navy personnel specialize in ship operations, submarine warfare, and aerial missions launched from carriers.
The army's equipment mainly includes tanks, artillery, and land vehicles. The navy, however, relies on ships, submarines, and aircraft carriers as its primary assets.
In terms of organization, the army is structured into units like brigades and divisions. The navy, on the other hand, organizes its force into fleets and squadrons.
The army often engages in direct combat and ground-based missions, whereas the navy plays a crucial role in controlling sea lanes and providing logistical support from the oceans.
