The Victoria Cross, in comparison to the Medal of Honor, is given out very rarely. Particularly these days, only VC's I've known of to be received have been posthumously because the acts have been that courageous. Anyone who doesn't die from the acts gets something less, like that Gurkha who fended off 30 Insurgents!
But the Medal of Honor.. Carry an Injured Afghan onto a Helicopter with no helmet on and you qualify straight away, but wait, you can only receive it when the President wants to look good so he can stand a chance of getting re-elected.
