...I have 2 groups of civilians "setcapture true" ...
I hope ya mean "setcaptive" .
They won't enter the vehicles unless ya set RESISTANCE FRENDLY TO EAST in the intel box

(thats the weather settings window in the upper right corner of the editor).
Now, I haven't tried this & I must confess that I dunno how / or IF it can B done at all, but if there's a way to edit the intel settings while the game is running, a trigger could do the job.
Off course ya can try the good old "assignascargo" & ...orderGetin True etc. but in this case I'm afraid the CIV's pretty much stick to the rebels & their ways of living

sorry m8 -
MAYBE.... a workaround could be to use a CIV truck & a "FAKE" soldier
