Try this..
First create a man. (it doesnt mather who he is because u're going to delete him when you're done.) In the init field of the unit type this exec "camera.sqs" When u now press the preview u will see nothing but a cross. Move around with W A S D. Up and down is Q and Z
Move to there you want the unit to stand, then press ctrl. (It is not enough to point the location with the cross. The camera must be where the unit shall stand.) Press ALT+Tab. Go to your operationflashpoint folder. There should be a file named clipboard. There it is something like this.

_camera camSetTarget [9973.44,104005.64,27.21]
_camera camSetPos [9973.44,4005.64,2.00]
_camera camSetFOV 0.700
_camera camCommit 0
@camCommitted _camera
What you need to consentrate on is this line:
_camera camSetPos [9973.44,4005.64,2.00]
Copy this part [9973.44,4005.64,2.00] (It will not be same numbers as here) and paste it into the unit you want to stand where the camera was's init field. Then type: this setpos [9973.44,4005.64,2.00]
Voilla! I'm not so very good in english, so if you need further explanation, just ask ;D
