Which chemical agents can the M4 Joint Chemical Agent Detector identify?

The M4 Joint Chemical Agent Detector is specifically designed to identify a range of chemical warfare agents, most notably nerve agents, blood agents, and blister agents. Nerve agents include highly toxic substances designed to disrupt the normal functioning of the nervous system, causing severe physiological effects. Blood agents disrupt the ability of the blood to transport oxygen, and blister agents cause painful damage to skin and mucous membranes. The detector is valuable for military and emergency response personnel in assessing and responding to potential CBRN threats, making its capability to identify these specific types of agents crucial for effective operational success.

Other options, while they mention harmful substances or categories, do not accurately reflect the intended purpose of the M4 detector. For example, toxic industrial chemicals may be recognized under some conditions, but they are not the primary focus of the M4's capabilities, which are tuned for military-grade chemical warfare agents. Similarly, while mustard gas and phosgene are significant in historical and specific military contexts, they fall under broader classifications (like blister agents and blood agents) rather than being specific identifiers for the M4. Antidotes are not agents that the detector identifies; rather, they are treatments for exposure to these chemical agents. Therefore, the emphasis on nerve, blood,
