Personnel have been briefed on the three reasons soldiers are vulnerable to disease. Personnel are trained on the seven major components of the medical threat to field forces. Training of unit personnel as members of an FST in the team's eight areas of responsibility has been completed when necessary. Reasons For Vulnerability. Harshness of the Environment.
Harsh environments are a part of military operations.
Leaders and soldiers must be prepared to live and fight in deserts, in jungles, in the Arctic, and everywhere in between. Natural defenses are reduced by exposure and fatigue. These defense mechanisms operate efficiently to protect against disease and climatic injury and are dependent upon our overall well-being. When soldiers are placed in high stress situations such as climatic changes, sleep deprivation, and irregular meals, they become more susceptible to illness and combat stress. We have increased vulnerability in the Army inevitably because the soldiers must stand in countless lines, load onto noise-hazardous aircraft which dulls their senses, and be expected to fight or otherwise perform their mission when they arrive.
