Which characteristic is NOT associated with a short-term height/caches?

A short-term cache is typically established for immediate use in tactical operations and is designed to be quickly set up to support short-term objectives. Characteristics such as being well concealed, quickly established, and tactical in nature are fundamental to the purpose of a short-term cache, which is to provide discreet and rapid access to resources whenever they are needed during operations.

In contrast, the defining characteristic of being "long-term in usage" contradicts the essence of a short-term cache. These caches are intended for temporary use and not meant for long-duration storage or reliance. Therefore, the characteristic of being long-term in usage does not fit the operational intentions associated with short-term caches.
