In military terminology, the acronym HE stands for High Explosive. This term is commonly used to describe munitions that are designed to produce a powerful explosive effect upon detonation. High explosive materials are characterized by their rapid reaction and ability to create a significant shock wave, making them effective for various applications, including demolition, artillery shells, and bombs.
Understanding the properties and applications of high explosives is crucial for military operations, as these materials can determine the success of specific missions by their ability to incapacitate targets or destroy obstacles. In contrast, the other options, while relevant in military contexts, do not correspond to the acronym HE. High efficiency relates to performance or output, heavy equipment pertains to vehicles or machinery, and hazardous environment can describe conditions but does not specifically relate to explosive materials.
