In combat movement, what is the movement style referred to when ensuring a unit remains undetected?

The movement style referred to when ensuring a unit remains undetected is stealth movement. This approach emphasizes the importance of being quiet and minimizing visual and auditory signatures to avoid detection by the enemy. Stealth movement involves techniques such as low-profile positioning, slow and deliberate movements, and utilizing cover effectively to obscure the unit from enemy observation.

In contrast, the other movement styles focus on different tactical objectives. Traveling is used for speed and can expose the unit to enemy sight, while bounding overwatch involves units moving in a way that one element provides cover for another, achieving a balance between movement and security but not prioritizing stealth. Traveling overwatch combines elements of both traveling and overwatch but still does not focus specifically on undetected movement as its primary goal. Thus, stealth movement is the correct answer as it is the technique best suited for avoiding detection in combat scenarios.
