Final answer:
A strategic point is any locality or area that provides a marked advantage to one combatant over the other, such as a high ground or chokepoint.
Step-by-step explanation:
The term you are referring to is strategic point. In military strategy, a strategic point refers to any locality or area that provides a marked advantage to one combatant over the other when it comes to seizure, retention, or control. It can be a geographic feature like a high ground or a natural barrier, or it can be a man-made structure like a fortress or a bridge.
A classic example of a strategic point is a hill or mountain range that provides a defensive advantage in terms of visibility, cover, and control of terrain. Another example is a chokepoint, such as a narrow mountain pass or a bridge over a river, which can be easily defended and restrict enemy movement.
By controlling strategic points, a combatant can gain tactical and operational advantages, such as better positioning, control of important resources or supply routes, and the ability to disrupt or block enemy movements.
