@Kontact:
Under the description of shooting at a barrier, it doesn't say that you compare the DV to the armor rating anywhere. Comparing the DV to armor is only mentioned in Shooting Through Barriers on pg. 166 of SR4A, but that is not mentioned in Destroying Barriers.
Now you're, right, I totally meant that the Guard1 picks up his weapon just like Guard2 did, but I didn't explicitly say that he did, so to be fair I'll just assume he didn't, so I'll redo his action.
