Q. How do I make a scud move its missile into the upright ready-to-lauch position at the start of a mission?
A. In the init field of the scud type
this action ["scud launch"]
note the space in scud launch. The scud is side East (not empty).
QED
Which all goes to prove
a) check your syntax!
b) if you want to know how to do something that's in an official mission, un-pbo it and find out. Which is what I have just done.
