Which term means being awake, alert, and aware of one's surroundings?

The term that means being awake, alert, and aware of one's surroundings is "conscious." This word specifically refers to the state of being aware of and able to think and perceive one's environment. When a person is conscious, they are not only awake but also engaged with what is happening around them, allowing for the appropriate responses and actions based on their observations and perceptions.

In the context of law enforcement and safety, being conscious is a critical trait, as officers must remain aware of their surroundings to respond effectively to situations, assess risks, and ensure the safety of themselves and those they serve. This state is different from simply being alert, which may imply a readiness to respond but does not necessarily encompass the full range of awareness implied by being conscious.
