Totally unimportant of course, but often when I'm reading prog dialogue I try to imagine how a character sounds. Dredd isn't a big problem - Karl Urban nailed it, in my book.
Johnny Alpha? Hard to know. I think the excellent short film of a few years ago is probably as close as you'll get - kind of posh London, him being a politician's son. (Though Johnny's speech patterns in recent years are far more English-sounding than his old cowboy talk.).
Is Durham Red from Durham? I think so, given that Wagner and Grant changed her name from Chelsea Blue because they didn't want her to have a Chelsea accent.
Danny Franks - we don't know what country he's from, but i would guess he'd have a similar accent to Johnny's. Kano - no idea. Maybe he sounds like Marlon Brando in Apocalypse Now.
Rogue Trooper for me is American. Don't know why - because he's a soldier I suppose, and most war films feature Americans.
Dante - I don't know. Can't really imagine him having a Russian accent. Or is he actually speaking Russian all the time, kindly translated for the reader? The British and American characters seem to understand him ok. Maybe they all speak Russian too. Or maybe it's a Sláine thing, where the Irish tribe speak the same language as Egyptian invaders, just because.
