Select a stack, and then a unit of that stack in the Stack Panel; hold your pointer over the Unit Power field (105 in this illustration), and the man-power values will be displayed at the bottom of the unit-counter where the unit name is normally displayed.
OK thanks. So I gather the manual is in fact incorrect and the CTRL button functionality has been removed? Must say that it was quite a handy command to have and common with the earlier games.
It changed with CW2, so, yes, the manual is wrong. I still find myself hitting <Ctrl> and then again, and again even harder, before I realize that it doesn't work like that anymore
