Which of the following is NOT an attribute of a good cache?

A good cache in the context of Counter-Improvised Explosive Device (CIED) practices is characterized by certain attributes that enhance its effectiveness and security. One critical attribute is that it should be available for immediate use. This means that when it is needed, it can be accessed quickly without undue delay, which is vital in various operational scenarios.

Well concealment is another important feature. A good cache should be hidden from potential discovery, meaning it can be stored in a location that is not easily visible or known to adversaries. This reduces the risk of it being found and compromised.

Inaccessibility also plays a role, but it is nuanced. While it should not be easily accessible to anyone besides the intended user, “inaccessibility” can refer specifically to high risks for unauthorized access, meaning it should be secure yet reachable when needed by the operators who set up the cache.

Highly visible, however, detracts from the purpose of a cache. If a cache is highly visible, it significantly increases the likelihood of detection by adversaries, thereby nullifying its function as a covert resource. Therefore, this attribute would not align with the fundamental principles of creating an effective cache, making it the correct choice as the option that is NOT an attribute of
