Your problem is most likely that you haven't imported the correct mods to get any of the campaign units. To do it, with your map open, go File > Dependences and add the Liberty (Campaign) standard. You can also do this in the create new map window.
We should really get a mod to sticky this. Otherwise I can imagine quite a few threads will open up asking this same issue.
I added them but I still cannot find the campaign units. I looked in subfolders labeled "Campaign", as well as the other available folders, but they don't seem to be there.
I see what you have to do now. You have to go New Map and set the depency to Liberty Campaign. I was just trying to look for them in the default blank map.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
