What identification method is usually employed as a last resort?

Visual identification is often viewed as a last resort because it relies heavily on the human element, which can be error-prone and subjective. In combat or operational scenarios, visual identification can involve looking at visual attributes (like uniforms, vehicles, or other distinguishing features) to determine the identity of a person or object. However, this method is typically considered less reliable compared to other, more precise identification methods, especially in high-stress or rapidly changing situations where the risk of misidentification can lead to significant consequences.

In contrast, target verification, combat identification, and electronic identification use more concrete data or systems to confirm identities. These methods can involve technological aids or established protocols that provide clearer and more reliable identification compared to visual means, making them preferable in most situations. As a result, visual identification is often used when other methods are unavailable or inconclusive, necessitating a cautious approach due to the potential for ambiguity.
