I just got a closer look at it, and I can narrow it down between 1974 and 1977. I suspected as much.

That is the only time it is seen in the film. I have one additional capture image of that scene but the kid on the bicycle is blocking more of the grille so it provides less detail.

I am having difficulty uploading the images to my server to properly retransmit them into the forum. I need to take care of some personal business so I will be away from the computer for a few hours. I hope to return for straightening out my contributions later this evening.

That Dodge ambulance is a B-Series, anywhere from 1971-77. A closer shot of the grille and I'll narrow it down further for you.

Pardon my being a newbie to the forum. I now realize that I forgot to create a new topic under which each of my images should have been posted.

Posting them as I have, all as replies following the first image I posted, is improper. I will create thumbnails for each of the images and resubmit them.

Your military vehicle (unknown) is either a Russian UAZ-469 or its Chinese clone, the Beijing 212; probably the latter as UAZs have four doors.
