The Gran Sasso raid refers to
Operation Eiche (German for 'Oak'), the rescue of Italian dictator Benito Mussolini by German paratroopers...
Drop a C47's worth of troops near an HQ, they run into the HQ, achievement! Yes need at least one side de-acked.
http://en.wikipedia.org/wiki/Gran_Sasso_raidAnd/Or go solo, with the player being a Chute... as in bail out from any plane, of course the pilot of the C47 also.
As a chute, PING the front door with pistol! (any of the four HQ entrances) Achievement! Yes this would require some de-acking a bit, the outside edge would be ideal.
Could also call it "Someone's knockin at the door, someone's ringing the bell, why don't you open it up, and let em in?" or "Seal Team 6" or "fighting on the front porch" or "pulling a Rambo" or "I'll be back" or whatever or whateva, its just something to do!
Fly a Storch in, land near the HQ and pick up ole Mussolini, then fly back to base - Achievement!
