Pattern Altitude
Most, if any, USAF bases don't have PARs anymore now that the newer planes have ILS onboard. I'm not positive but the only PAR equipment in the USAF is the mobile radar units (see my profile for a pic of one, the MPN-14) assigned to Combat Communications
units at Robins AFB (5th CCG) and ANG Combat Communication Squadrons. You might be able to do a Surveillance Approach though.
USAF guys needing a practice PAR go to Navy fields. They are about the only ones still doing them. (in the US)
