Which of the following indicates an increased threat level of IEDs?

The presence of evidence from previous IED incidents is a strong indicator of an increased threat level. This suggests that the area has been a target for such attacks in the past and may be viewed as a continuing target for future incidents. Historical patterns provide valuable intelligence for assessing current risks, as they reflect the tactics, techniques, and procedures used by those who might plan future attacks. Understanding this context allows security forces to enhance their vigilance and deploy resources more effectively.

In contrast, decreased activity in the area might suggest a lull in hostilities or a decrease in threats rather than an increase. Increased civilian patrols and heightened community awareness events typically represent proactive measures taken to enhance safety and awareness, which could actually serve to deter potential threats rather than indicate an increase in IED threats.
