Which of the following should NOT be used as cover?

Gas pumps should not be used as cover during a confrontation. While they may provide some level of obstruction, they pose significant hazards due to the presence of flammable materials. In a situation involving gunfire, the risk of explosion increases if bullets strike the fuel tank or the surrounding infrastructure. Thus, using gas pumps as cover is highly dangerous and not advisable.

On the other hand, utility poles and buildings can often provide solid cover, as they are typically more substantial and can withstand ballistic impacts, offering protection from incoming fire. Fire hydrants may also provide some degree of cover, although they are not as effective as other structures due to their size and the fact that they can be easily damaged. Understanding the limitations and potential risks of different types of cover is crucial for maintaining safety in potentially life-threatening scenarios.
