Give the US Army some credit: their solution to the fact that they were ill-trained for fighting in jungles was a simple one. They’d simply get rid of the jungle. While there was some earlier testing of herbicides in 1961, it wasn’t until 1962 that large scale deployment of the Rainbow Herbicides – Agents Pink, White, Purple, Green, Blue and (most infamously) Orange – began. Over the course of ten years, until 1971, nearly 20 million gallons of assorted herbicides would be used.
The policy was largely a failure at its stated goal, but it did do wonders for the bottom lines of various military contractors and led to a boom in birth defects among the children of soldiers and civilians exposed to it on both sides in the years to follow the war.

Orange Crush — R.E.M.
On the evening of January 2, six men were captured outside the fences of the US Marine base at Khe Sanh, in the Quang Tri province of Vietnam, apparently performing reconnaissance for a planned North Vietnamese attack.
A defector carried information about the attacks to the US forces on January 20, and the attacks themselves began the following day. The US and allied forces quickly joined battle, but were surrounded and besieged. For the next two months, the siege went on, until American forces broke through and relieved the base in March.
The American forces recorded a total of 730 soldiers killed in action, with a further 2,642 wounded and 7 more missing in action. Casualties on the North Vietnamese side are estimated as between 10,000 and 15,000.
