The Victoria Cross should only VERY rarely be awarded. Actually, you'd be better off not including it as a possible award at all, than to have it awarded too easily.
I'd hate to finish a sortie, read the debrief and think "Oh, I've won a VC. That's nice." The vast majority of British servicemen and women would never see such an award, and to have one pop up mid-campaign would be incongruous to say the least.
I like the sound of "Mentioned in Despatches" though. That has a nice ring to it.
