The first known weapon was made of stone. These weapons are sharp stones next to the oldest human ruins hundreds of thousands of years ago. (Matthews) In Croatian Clapina, archaeologists have discovered a human bone of 120,000 years ago. In some bones, they found traces that might have been caused by stone spearheads, and they found the oldest sign of the war if their discovery was true. For the development of weapons, war has experienced tremendous change throughout history.
Evolution of weapons is not the only thing that changes war. This is the distribution of weapons. Throughout history, states often fight each other as to the symmetry of weapons. For example, in the First Gulf War, Saddam Hussein tried to defeat a traditional industrialized mechanized American army with a traditional industrialized mechanized Iraqi army. The quality and quantity of American technology was dominant. However, in the Second Gulf war, the rebels performed an asymmetric battle to crack down on high-tech US weapons using low tech assassination, destruction and terrorism. The enemy's tactics will lose its benefits only when the United States has adjusted its technology to cope with the new threats. Of course, training, morale, figures, will, and politics will also contribute to the results of Iraq, but the nature of the technology will lay the foundation for struggle.
In addition to developing weapons that gained hints on recent Star Wars, some of the past technologies are becoming a part of today's daily lives. With the advent of robots, a series of excellent techniques are designed to restore the function of the lost part of the body during battle. Think of it as a hardware component lost in battle. A hardware store that can be regarded as a replaceable part. Do not finish, the holographic image may soon be a reality. In Star Wars scenes, a robot called R2D2 projects a 3D image called R2D2 onto the 3D image of Skywalker with the help of Obi-Wan Kenobi. Holograms are becoming a part of reality in the near future
