Thanks for the comments, Al LaFleche.
Well, the scene is set out to depict the launcher being made ready for launch some KMs behind the front line. The two commanders are meeting to clarify and coordinate final things before action commences later.
The launcher has not fired in this position yet. There are no sod/burn marks on the rails. Launch might be hours away. By the time of firing the PT-76 and launcher crew would be at a safe distance or in cover.
You are right about the netting. That would have to be removed before firing by the crew. It could be used by the crew to cover the launcher when not getting ready to fire. Anyway, I agree with you that it cannot be placed that far back when firing.
Al LaFleche and John, You are right about the weather. Most pictures from the time indicate more rocky dry terrain. However, the terrain can be muddy - especially in the Golan heights area. I have read stories from some of the Israeli soldiers fighting there and they compared it to some of the fighting in the mud of WWI. I cannot remember the names of the soldiers, but their stories were later made into a movie.
Below are some recent pictures from the Golan heights. I know these pictures are much more recent than 1973, but they indicate that it can definently be muddy.
