To be fair the FI campaign really was very much a Navy/Army affair. The Navy remember were the people who convinced Thatcher the islands could be retaken and then more or less isolated them and managed to get the troops onshore. Once the troops were there ashore it wasn't going to end well for the Argentinians. The RAF weren't that involved in most of the critical actions although bombing Stanley early did keep the Argies from using it for fast jets.
but then there have been other campaigns where the RAF have led the way - such as in the Middle East and the Navy have been doing logistics. That's why you have all three armed services.................
