A vig of a SAS (Special Air Service) agent going into a hostile base. He will then extract information about nuclear missiles that are supposed to be launched in several days. If possible, he will stop the launching. He will also cripple the base as much as possible to confuse the enemy.
The SAS agent getting ready to grapple down a barley seeable rope.
The unsuspecting guard.
That's all, it's big for a vig, but still, it's not all that big.
Okay, well, the guard could clearly see him (he sticks out like a sore thumb), the rope is obvious, and he could probably swim that distance. Another thing, the SAS never operate as individuals, they always operate as a team, so a minus for that. Colours of the base are too random.
