Finally, some images that Silvia emailed a while ago, I can now post.
THIS IS A GRAPHIC color photo. These large gaping wounds are the result of serious injuries.

And an outside scene shows how rough things were.

This is an Army video. At 4:27-4:38, the jet guns are pressed into the arms of each recruit without any attempt to clean them between each injection.
In the right menu, there are some other recruiting videos. This one is from the Marines. It doesn’t show jet guns but does show dentist exams were performed, no gloves of course, at 5:42-5:48.
This Is Parris Island (1970) (Youtube LINK)
And I’ll get up a report Silvia sent us on jet guns and Frank has also some items of interest to post here.

On that beautiful jet gun picture you can see that the filter was missing.
Your Aussie brothers took some great pictures and they don’t mind sharing with us. You really must look at their Agent Orange pictures to see if there’s anything you can use. They have some great pictures of guys (diggers) eating and filling their canteens with contaminated water. Some great closeups of helicopters with sprayers and on some of the pictures they point out American planes on the background landing on a strip. So it puts Americans in the same places they were….and they took over 100 pictures.
