You're damn right chains make a difference. It's crazy, especially with v-tread chains. I don't use them real often, but there always there when needed.

Not to divert from discussions concerning how to get stuck rigs unstuck, but here is another shot of the 7 ton near Haditha with an Army Psyops Sgt I got to know pretty well. I don't remember how they got it out, but am sure it required support from Al Asad as well.
