What warfare type targets enemy surface combatants and merchant ships?

The correct choice highlights the specific type of warfare that is intended to engage and neutralize surface vessels. Anti-surface ship warfare focuses on using various assets and tactics to target and disable enemy surface combatants, which include warships and naval vessels, as well as merchant ships that may support an enemy's naval operations.

This type of warfare is crucial for maintaining control over maritime regions, securing shipping lanes, and ensuring that opposing naval forces are kept at bay, thereby protecting friendly operations. It involves using surface ships, submarines, aircraft, and land-based systems to engage targets in this category, demonstrating a tactical focus on surface engagements.

Understanding the nuances of different warfare types, such as anti-air and anti-submarine, is essential, as these focus on different threats (aircraft and submarines, respectively). However, anti-surface ship warfare is unique in its direct approach to confront and neutralize surface threats, making it the relevant choice for this question.
