Final answer:
When responding to an active shooter, the contact team should immediately react the sounds of gunfire.
Step-by-step explanation:
The team should not ignore or dismiss gunshots, as this could put themselves and others in danger. When gunfire is heard, it is crucial for the contact team to take immediate action. They should assess the situation, find a safe location, and quickly alert law enforcement.
It's important to remember that in active shooter situations, time is of the essence. Every second counts, and the contact team's response to the sounds of gunfire can help save lives. So therefore the contact team should immediately react to the sounds of gunfire to ensure safety in active shooter situations.
