Vernon99/Viszla - Your negative comments surprise me. Does that mean that there are no Rapier units based in the Falklands now? No RN ship with sea to air capability in the area? No ground based air defence radar unit? Just these three items would amount to a very significant improvement on the air defences of pre invasion 1982.
Double Zero - You sound more optimistic!
Not sure who mentioned an airborne landing but you would have to pick a calm day otherwise half your force would end up in the sea and the other half would have broken bones after being dragged across the LZ! Para units travel light and are shock troops, you would still need a sea tail to back them up, arriving within hours of the drop, assuming any transports were left in the sky and able to drop.
