When they got to Italy they were given a mission that the entire Fifth Army couldn't seem to accomplish: take Mount Difensa. Difensa was occupied by the Germans with a bunch of 88s. It rose over an important road so taking this mountain meant that the allies could get their supplies through and continue the push. But Difensa had held them up for three weeks. Rather than do what everyone else had tried and go up the front of the mountain, Frederick decided they would simply climb the sheer cliff in back because the Germans would never expect it. Now I thought this scene in the movie was just added for color but then I saw this:
This is a Forceman loading up with supplies so that he can climb a rope straight up a sheer rock face 1000 feet high. So the plan was that the entire Brigade would load themselves up, climb the ropes in three hours, then kill every German in sight. I don't know about you, but if I just put that pack on I wouldn't be able to jump a foot let alone climb 1000 feet and then be expected to engage the enemy. And this was a climb that was only attempted by two people before; one died trying and the other had to be rescued. But the Force were different and thought nothing of it. Anyway, the Force got to the top lickety-split and did in three hours what Fifth had tried for three weeks: they took Difensa. A German captain was captured at the top of the mountain and said "You can't be here! It is impossible to come up those rocks!" Shut up Kraut, you don't know the 1SSF. Anyway, after that, everyone--especially the Germans--knew about the Black Devils and they were given all the toughest jobs. They never gave up an inch of ground. EVER!
