I thought you might be thinking of contamination...by agent orange or some other horrible chemical that was used during that time frame but NO....
That's one thing I was trying to cover by saying "better maintained and in better condition..." above.
Decontamination of troops, equipment, supplies, explosives, etc has been of the utmost priority in the militarty since the late '70s. All troops are trained in decontamination procedure and specialists ensure that equipment, supplies, etc within the supply chain today are safe.
Also keepin mind that Agent Orange was a de-foliant that acted upon organics only. It could contanimate skin, clothing, tarps, etc...but could NOT leave a lasting residual on equipment, metals, or other such solids.
Again, I can personally attest to the relative safety of handeling Vietnam Era equipment and supplies and as a Vietnam Veterans Association associate member, I can also tell you that I am not aware of any recent outbreaks among our troops of Agent Orange related disorders.
