An army (from Latin arma "arms, weapons" via Old French armée, "armed" [feminine]), ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or state.

A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields.

The Army primarily uses tanks, helicopters, and all-terrain vehicles suited for land warfare.

Apart from combat, the Navy plays a crucial role in disaster response, humanitarian aid, and securing international waters against piracy.

Navy ships typically engage in patrolling, enforcing blockades, and launching missiles during combat scenarios.

The Navy contributes to international diplomacy by showing a presence in international waters, participating in joint exercises, and aiding in international maritime law enforcement.

Recruitment for the Army often emphasizes physical and tactical land warfare skills, while Navy recruitment focuses on technical skills and adaptability to maritime environments.

The Navy uses advanced technologies like nuclear submarines, advanced radar systems on ships, and naval drones for various operations.

Army operational strategies focus on gaining and holding ground, while Navy strategies are about controlling sea lanes and projecting power from the sea.

The Army supports civil authorities by providing manpower and ground resources during emergencies, while the Navy can offer logistical support from the sea.

The Army's environmental impact often involves land degradation due to military exercises, while the Navy's impact includes issues related to marine ecosystems.

In joint operations, the Army and Navy coordinate to combine land and sea capabilities, enhancing the effectiveness of military strategies.

Army personnel typically live in barracks on land bases, while Navy personnel might spend months aboard ships or submarines with distinct challenges like limited space.

Career progression in the Navy often involves specialized training in technical fields related to maritime operations, whereas in the Army, it might focus more on leadership and combat tactics.

Historically, the Army has played a key role in shaping national borders through wars and ground campaigns.

Both branches offer educational benefits, but the Navy often provides more specialized technical training due to the complexity of naval equipment and operations.

Public perception can vary, but generally, the Army is seen as a symbol of national strength and land defense, while the Navy is often viewed as crucial for maintaining global peace and maritime security.
