I think Swen said in the let's play that one campaign unit will be 4 units on the RTS map. And I guess you can't take the units you produced in the RTS mode with you into the campaign mode for balancing reasons.....
I think there is some mechanism/algorithm which measures how many units you lost in battle and therefore it measures the respective units lost in campaign units....
