This is definitely an error in the printing, and it most probably should have read 'Gain control of the Orange Region' instead.
I can only point you to this post:
Two considerable problems with the production have been discussed on the forums. In the Canadian edition at least, the first page of the rules is missing (it can be downloaded from BGG). And there are one or two mis-prints or just poor edits through the rest of the rule-set. In particular, scenario Three grants a free "Green Region" objective to red right at setup. I'm sure that "Green Region" was meant to be "Orange Region." This would create perfect parity between Blue's situation on his western front and Red's on his eastern, and it would encourage advancement toward the otherwise obscure "Eliminate the Neutrals" objective. If this isn't the case then the layout of the central European theatre is a remarkable co-incidence.
