Three points -
any plan that didn't involve disabling the runway and thus the air cover [using covert insertion] is probably doomed so let's assume it. They are never going to succeed if they go faffing about Sth.G again and even HMG isn't going to be *that* asleep twice... surely?
second - what's the opposition going to be like. Have they seriously re-equipped since 82 with longer endurance fighters and anti-surface than Etendards and Skyhawks?
third - would President Tone have the bottle to tell one of the attack sub commanders to sink what needs sinking, or smack an Argentine airfield or three with Tomahawk?
