How many classification characteristics must a contact have to be considered mine-like?

To be considered mine-like, a contact must exhibit three specific classification characteristics. This criterion is derived from the need to accurately identify objects that exhibit behaviors or features similar to those of actual mines, which helps in ensuring accurate assessments during mine detection operations.

Having three characteristics allows for a more comprehensive evaluation of the object, enhancing the likelihood of distinguishing it as a potential mine. These characteristics might include aspects such as size, shape, material composition, or behavior in a certain environment. The emphasis on multiple characteristics ensures that there is a reliable basis for classification and avoids misidentifying non-mine objects as threatening. In contrast, having only one or two characteristics may lead to ambiguity and could result in either false positives or negatives during identification. Thus, the requirement for three characteristics ensures a robust framework for classifying contacts as mine-like.
