We have run into similar issues over the past decade.  The .mil domain typically
gets pretty defensive when they pick up on any amount of probing, especially
from .edu domains.  My experience has been that if you can verify the offending
systems are clean, and you are talking with the right folks, you can get the
block removed - if not for your entire network, then for the subdomains that
require this access for specific tasks.  I do (did) have a good contact that
was very responsive and was able to open the .mil domain up to Harvard traffic.
I will see if I can dig up his contact info and forward it along.

We have had zero luck trying to deal directly with the Army
administrators. As a result of the impact on several campus groups, my
administration is looking to escalate this into the political realm. If
possible, I would like to give them an idea of how many other
institutions may have been affected.

Is anyone else encountering this problem?

One of the administrators at the Army NOC indicated that most of the
.edu IP space was being blocked. I would like to have a more solid
foundation before I take that type of assertion to my administration.
Thanks in advance!
