Chemical Warfare
This is what Chemical Warfare looked like when the war was close to the end and when people saw them doing this they were so scared.
Chemical warfare was very popular in the Vietanm War because of how fast it can kill. It involves using toxic chemicals and other substances as weapons to kill in mass amounts. This type of warfare is also known as "weapon of mass destruction". This type of warfare was different from all of the other types of warfare that they used in the past and what other countries are using to fight right now. This warfare was so much more effective because in a quick amount of time the chemicals can probably wipe out a whole town in a few minutes. That is why so many countries startes to use this method sincew the war when no one saw this type of battle before and when they saw it for the first time they were amazed and wanted to start to fight with this. If you were to use these chemicals you would have to wear a full body suit to protect you from these very dangerous chemicals.
