PN,
Sorry old chap, I was thinking of Mirage III in the OCA role sweeping for their strikers by taking on FRS 1 flying the DCA role over San Carlos.
The pickle for the OCA in this case is that they couldn't go in at medium level against the Sea Dart threat which would force them low, into the AAA and Sea Wolf MEZ, that those brave strikers were having such a hard time with.
