The script to Rambo 3 has three mentions of Mujaheddin in it. Two of them are in the following section:
"What you see here,
are the Mujahedin soldiers,
holy warriors.
To us, this war is a holy war.
And there is no true
death for a Mujahedin,
because we have taken our last nights,
and because we consider us already dead.
To us, death for our
land and God is an honor.
So, my friend,
what we must do is to stop this
killing of our women and children.
If getting this man free,
so he can tell to the free world, and
tell what happens here, is necessary
then of course we will help."
I'm not sure if that's praising or exalting, but it wasn't damning in the context of the movie.
My favourite (and probably most prescient and ironic) quote from the movie is:
"You can't defeat a people like that.
We tried. We already had our Vietnam!
Now you're gonna have yours!"
