How about "Little Round Top" Defense? This is the name of the decisive battle on the second day of the battle of Gettysburg. The Defenders of Little Round Top were the 20th Maine regiment, New Englanders! In this battle, the Maine boys withstood two valiant uphill charges by the confederates as they tried to flank the Union line. The third charge, was met by a surprising bayonet charge by Col Jashua Lawrence Chamberlain. Chamberlain went on to become Governor of Maine and president at his alma mater Bowdoin College
Our defense line is definitely not little, and isn't Top Round a cut of beef?
Of all the names I have seen so far I like The Fortress and Devestation Inc as the best.
