I have no idea where to put this but I have a large base that can easily be expanded upon or contracted. If the admin want to move this to another area have at it.
It is a medium size US base but that could be changed to East with ease. Hope you guys enjoy it. The base would be great to withstand an onslaught of enemies.
Put the folder where ever your user created mission are. Directory should look similiar to this.
C:\Documents and Settings\XXXXXX\My Documents\ArmA Other Profiles\Ironman\missions\
