Hmmm...Wolverine is their only hope (unless Obi-Wan joins them...sorry bad Star Wars joke). I'd give a slight edge to the 1500 guys. Assuming they're mindless or something and won't run away, Wolverine's healing isn't instantaneous, and 1500 guys could come up with a lot of stuff to do that would hurt (even Wolvie...the guns, tanks??, acid, etc. was mentioned earlier).
