Which is a primary feature of a hill in military terminology?

In military terminology, the concept of "high ground" is critical for strategic advantage. A primary feature of a hill is its elevation compared to the surrounding terrain, which offers a superior vantage point. Occupying high ground allows military forces to observe enemy movements, control lines of sight, and provides a defensive advantage, making it harder for adversaries to engage effectively.

High ground is often associated with tactical superiority as it can influence the outcome of engagements. Forces positioned on elevated terrain can focus their fire downhill, covering wider areas and offering greater protection against incoming fire. This advantage is particularly crucial in combat scenarios, where visibility and range can determine the effectiveness of operations.

In contrast, low ground, flat terrain, and difficult terrain do not provide the same level of strategic benefits as high ground does, making high ground the essential feature when discussing hills in a military context.
