War is used to test every kind of technology
It's a sad, but well known fact that war is good for business. Companies that manufacture weapons need to prove their technology works. So small wars are excellent testing grounds for both the current and new ideas. If everything performs as it should, other governments around the world will buy the systems for their own armed forces. But wars are not just about the latest guns, armored vehicles, ships or airplanes. They also test the people who fight. Despite the drive to keep fighters safe by using drones and other systems to kill the enemy from a safe distance, human beings still have to go face-to-face with the enemy in combat. Once you put people into real fighting situations, they get injured. For a while, this was not a problem but, as the engagement in both Iraq and Afghanistan has continued, the strain on the volunteer forces has increased. Military personnel are being rotated more rapidly with less time to recover from injury. As this is being written, President Obama is considering whether to increase the contribution to the NATO force in Afghanistan. If an increase is authorized, this will put even more strain on the armed services.
