To stop worrying perhaps a cold beer and a pipe.
An article from an American newspaper. It is belived the North Vietnamese, or was it Viet Cong, have been drugging their troops before they send them into battle. North Vietnamese probably as according to the statistics and body counts the Viet Cong have already been wiped out many times over.
A few days later another article rectified the first. What had been thought of as drugs turned out to be balls of sugar. Given as an energiser to the undernourished soldiers before going into battle. Their drugged state was not in fact drugged, it was dazed. They were the survivors of a B52 bombardment walking around in a zombie like manner. Of course those in the centre of a B52 attack are killed outright. The next circle are killed indirectly by the blast. The outer circle are reduced to these Zombies. The living dead for any unfamiliar with the term.
