A few hypothetical questions about the Falklands War

#1. What AAM were the Argentinians armed with?

#2. Can anyone give me a simple comparison of the Sea Harrier and the Mirage III in terms of air to air ability, radar, and survivability.

#3. Is it possible to arm a Mirage with a AA-7 Apex?

#4. Could the Argentinians bought AA-7’s before the Falklands War (not did they, but could they have)?

#5. If the answer to #4 is no then could they have bought any other medium range (15 km+) missles from anyone?

Thanks,
Ghent
