Army Criminal Investigations Special Agent work is not for everyone.

They are expected to find evidence within an investigation, whether it is at a crime scene or during an interrogation. The job requires agents to be active listeners who can prioritize the information they receive.

This may include but is not limited to armed or unarmed combat, tactical operations, performing vehicle pat-downs, use of deadly force when necessary, responding to assaults with firearm or other lethal weapons, extreme physical or mental stress (including assisting in rescue operations), imminent destructions of property with the potential for death due to explosions, fires (arson), natural disasters (hurricanes). Occupational injuries can occur while performing duties. These include but are not limited to nerve and soft tissue injuries, back injuries, eyes-staring-in-the-sun injuries, heat illness, heat exhaustion/stroke.
Quick decisions ability
Quick decision-making ability is needed in order to make split-second decisions in emergencies and handle stressful situations. Being able to operate safely with lethal weapons is a requirement for this MOS. Active shooter incidents will be a regular occurrence requiring the ability to respond immediately at short notice. In the event that an agent realizes he may need to react, he must make his decision in moments rather than considering it for hours or days on end.

The ability to make quick decisions is also required as it could mean the difference between life and death. Agents endure long periods of physical exertion in order to track suspects or gather evidence because they understand the importance of their work to society.
