As such, I think half of one's units would be the way to go.
in reference to daivahataka's comment- Being able to kill double UP is nice in theory, however that only sets a person back for two days. In the grand scheme of things, two days is not very long at all. While it would be sad to see someone lose a ton of units overnight, it is a war game and should be expected. As long as people know the rules of the game, they can plan for it and make the best of any given situation.
But remember, this is AFTER you've already wiped out all their defence troops, so you'll probably be looking at a much longer rebuild.
