During MAC/SCAR coordination, which step designates the SCAR and assigns others to the SCAR net?

• A. ACU turnover
• B. Surface contact report
• C. Check-in brief
• D. SCAR designation and net assignment

Answer: (D)

The key idea here is creating a single focal point for coordination and organizing who reports to whom. In MAC/SCAR coordination, it’s the step that formally designates the SCAR and assigns units into the SCAR net, establishing who leads the SCAR and which units participate in that network. This sets clear authority and a common reporting structure, so all surface contact information is collected, filtered, and distributed consistently through one node.

Why this is the best fit: designating the SCAR and assigning the net provides the necessary leadership and communication framework. Without it, there would be no officially recognized SCAR to coordinate reports, and units might drip-feed information into multiple channels, creating confusion and duplication.

What these other steps do instead: turnovers are about passing control from one team to another during shift changes; a surface contact report is the actual data about a contact, not the act of organizing who reports it; and a check-in brief is an initial update to enter the operation, not the step that defines the SCAR or assigns nets.
