The Kent State Massacre is named after a calm protest uprooted when guards killed and wounded students by opening fire on a mass of students as they gathered on the Kent State campus (Encarta). Events such as the Kent State Massacre enraged Americans more than ever causing violent riots and outbreaks. Meanwhile, America's position in Vietnam worsened. More and more were sent, and more and more troops were killed. America's great offense was tattering down and guerrilla warfare on unfamiliar terrain hampered soldier performance. The war then quickly switched over and put more weight on air attacks and bomb raids. Helicopters became America's best friend as they were a brand new invention that had not previously seen much use. The helicopter made landing and exiting in rough terrain easier than any other method seen before by the United States military. Other weaponry made its debut in the Vietnam War. Spurred from the second world war, where tanks were introduced, the anti-tank missile launcher was a key weapon for all countries to develop. The Vietnam War was the first war that the anti-tank missile launcher was effectively used. Standard guns also were changing; they become lighter in weight, more accurate, and able to function better with less maintenance and malfunction. All of these new, and newly perfected, weapons made the Vietnam War an unfamiliar territory for everybody as the death toll soared through the roof. More troops were sent, more black troops. Racism raced through the veins of many white Americans at this time, and blacks still felt discriminated against by the government and the people of America. All of this as more black troops were being put on the battle front to fight. Black gangs erupted and dodged the draft, became violent, and held to one another very closely. This was the first sign of gangs in America, as we see gangs today. Many black Americans did not understand why they were being force to fight and die for a country that hated them.
