Axis and Allies Pacific Modifications for J1 - by various authors - Pattons3rd's rule for J1 #1 The Allies defend at a '2' during the first Japanese turn. Allies defending at '2' instead of '1' would force Japan to be much more picky about her targets, or run the risk of either spreading herself too thin, or even possibly losing one or two of the encounters. Pattons3rd's rule for J1 #2 / Jan de Roo's rule for J1 #1 Allied units which defend at a '1' or '2' normally, now defend at a '1'; Allied units which defend at a '3' or '4' normally, now defend at a '2' during the first Japanese turn.
