You're absolutely right there, Mace, the "Rupert" voice acting is bloody awful, but funny in its own way, as it appears to represent how game developers from Eastern Europe believe a member of the British officer class speaks. It's not so much the bad voice acting as the grisly writing, which overstays its welcome by about three minutes with that "it's the waiting" monologue, which is then repeated 2 missions later! Judging by his voice, the character you play is less of a "Rupert" and more of a "Darren".
Still, great campaign though, good SP missions. With AO and BAF they have finally gone for military realism rather than cinematics.
