Make sure that y'all have firewalls. Has anyone ever heard of them?

It appears to be a navy training procurement document for this company to teach the navy hacking techniques. The url didn't work either, it was too long. This one does.

My firewall blocked them again, that's twice this evening so far. Would it just be random, or why would they care about my computer?
