If a parent opts out of the public, non-consensual disclosure of directory information (or any subset of such information), must the three data elements be released to military recruiters upon their request?

If a parent opts out of providing directory information to third parties, the opt-out relating to name, address, or telephone number applies to requests from military recruiters as well.  For example, if the opt-out states that telephone numbers will not be disclosed to the public, schools may not disclose telephone numbers to military recruiters.
