Block 30, at my old base we had CAP members, both cadet and senior, visit us all the time. Never, have I seen any of the senior members...even those who are retired officers demand a salute from any military member. In the highly unlikely event that kind of situation should transpire kindly remind them that AFI 10-2701, Organization and Function of the Civil Air Patrol, states the folloiwng regarding their percieved rank status as CAP members (I've underlined the important parts) :

1.3. Status of CAP Personnel. CAP is not a military service and its members are not subject to the UCMJ. CAP members voluntarily perform Air Force-assigned missions. CAP membership does not confer upon an individual any of the rights, privileges, prerogatives or benefits of military personnel, active,reserve, or retired. While CAP is not a military service, it uses an Air Force-style grade structure and its members may wear Air Force-style uniforms when authorized. Air Force protocol requirements do not apply to CAP members.

1.3.1. CAP Grade. CAP uses military style grade for its membership at the discretion and approval of the Air Force. CAP officer or noncommissioned officer grade does not confer commissioned or noncommissioned officer status. CAP personnel have no authority over members of the armed forces.
CAP members who are active, reserve, and retired members of the armed forces will be treated according to their CAP status when acting in a CAP capacity. The Air Force has authority over the CAP grade structure.
