Actually, a number of the .mil zones are exceptionally broken, and
pacom.mil is no exception. :-)

The .mil TLD servers seem to have loaded the entire zones and are
serving borked zones as a result.  For example, ask the TLD about
www.pacom.mil:

$ dig @PAC1.NIPR.mil. www.pacom.mil

; <<>> DiG 9.4.3-P3 <<>> @PAC1.NIPR.mil. www.pacom.mil
; (1 server found)

And if you ask for an NS record for pacom.mil, it'll give you that,
but without an additional section despite having the answers, because
it thinks it is the authoritative for that zone (I'm guessing that
explains the behavior but don't know their software).
