The first (above and right) was F-5E BuNo. 160796, wearing a three-tone blue camouflage scheme and carrying bort number "24."  This airplane has something of an interesting history, having originally been built by Northrop in 1973 for South Vietnam.  In 1975, as the South collapsed, this airplane was one of a handful of Tigers to be spirited away to the United States before the arrival of the communists.  The USAF gave it the serial number 73-900 and flew it as a dedicated air-to-air "threat simulator" in its Aggressor program.  Sometime before 1987, it was transferred to the Navy and given the BuNo. 160796, serving with several fleet adversary squadrons (including VF-126 "Bandits" on the west coast and VF-43 "Challengers" on the east coast).  Since 1996, it has been operating with VFC-13 out of NAS Fallon, NV, again in the adversary role.

The second aircraft (below) was F-5E BuNo. 741556, which was painted in a two-tone blue-gray tactical scheme and carried the bort number "12."  It too spent many years as a USAF Aggressor, although unlike its wingmate, it never served with a foreign air force.  When it was transferred to the Navy sometime before 1992, its USAF serial number (74-1556) was simply translated directly into a Navy BuNo.  Before joining VFC-13 in 1996, it was operated by VF-45 "Blackbirds", the Navy's adversary squadron at NAS Key West.
