Noooooooo!!!! (Sorry Stevie!) Please let's avoid some hideously complicated pictorial solution. Cunning typography is the answer!
I certainly think use could be made of the 'H' and the 'A', particularly their cross beams, but please please PLEASE, not 'pretty pictures', or anything illustrative that pins us down. This is meant to be a LOGO of a no-shit, action-taking organisation. The logo therefore needs to be simple.
