In the Navy we had interesting rules for passwords. I don't remember the actual minimum character length but we had to have a mix of capital & lower case letters, numbers, and symbols in the password.
On my second ship we also had special software we used to try cracking passwords. If the software cracked your password you had to change it. The system won't let you reuse old password but... if the admin does it for you then that's fine. It's not recommended but you won't get punished for it by the command.
Although I have seen a couple of Navy systems that also check to make sure you're not just tacking on an extra character to your old password. So if you used say password1 the system won't let you use password11 and might not even let you use password2 either.
But the real problem I have these days is that... many systems don't like my classic military passwords. Not because they're recycled passwords (the system can't check my navy passwords after all) but because... they're too complex.
