One small nuke is a hell of a lot easier than trying to lay charges
on buildings in a plant, plus of course the fact that you don't
actually need to enter said target.
But as has been pointed out, I wouldn't put much hope on getting
out alive on a mission like that.
The other thing that was obvious in the article was actually getting
to the target with the thing on your back. Heavy packs with odd
shaped things do not make for either quiet tactical movement or fire
and movement if contacted.
