From the publisher's website: "A lot of people started asking if we could produce a version of FUBAR suitable for the increasingly popular 6mm scale. Here is the development draft of what we have done so far." This can help FUBAR players to tailor their games from the 25/28mm generic base FUBAR to a more wide 6mm battlefield. With the inclusion of some rules for vehicles, this ruleset does not differ a lot from the basic one. It is obviously a one page ruleset in the FUBAR philosophy.
