Someone really needs to take a stand against those flathead screws. There's really no reason why they should still be used. They get the job done in the end, but there's a lot of dickery involved that's circumvented by the additional stabilizing support of the Philips head. There was no slippin' and slidin' on his watch.
And while I mean no great disrespect to the Empire, I will say that for having an army that at one point was comprised almost exclusively of the clones of a legendary bounty hunter, Storm Troopers only seem to be sufficient at getting confused, sucking, and occasionally laying down some mean suppressive fire.
