What is the meaning of bunkers?

Bunker has several meanings:

1) In military usage, a bunker is a small fortified structure with thick walls and a roof, used to protect soldiers from enemy fire. Bunkers are typically made of concrete or earth and can be located on the ground, underground, or even in trees. Many military bunkers are specially equipped and provisioned to withstand extreme conditions, including radiation, fire, and enemy attacks from the ground, sky, or water.

2) In golf, a bunker is a hazard consisting of a sand-filled hollow or depression in the ground. Bunkers are usually located near the green and are meant to be challenging obstacles for golfers.

3) In construction, a bunker is a large container used to store fuel, oil, or other liquids. Bunkers are often used in industrial and commercial settings to provide a secure and efficient way to store and dispense these materials.

4) In some regions, bunkers can also refer to natural caves or rock formations that have a protective or shelter-like structure, such as underground chambers formed by erosion or volcanic activity.

5) In the context of sports, particularly American football, a bunker refers to the area on the sideline where players and coaches sit during a game. The term "bunker" is used to describe the team's bench area or the sideline area of the field.
