What is Merchant Navy?

Merchant Navy refers to the commercial shipping industry responsible for transporting goods, passengers, and raw materials across the globe via sea routes. Unlike a country's navy, which focuses on defense and military operations, the Merchant Navy is involved in trade and commerce, playing a vital role in the global economy. The professionals working in Merchant ships are called as mariners, seafarers, seaman or sailor.
