The rail gun, as my friend Dan Newlin explains, in addition to the surge in drone strike use, suggests an evolution in military tactics on behalf of the United States. Rather than putting the lives of soldiers at risk, engaging perceived enemies with long-range projectile weapons has emerged as a favored method of combat. Whether or not being removed from immediate action will facilitate a greater reliance on long-range weapons or military aggression on the whole remains to be seen, but is a progression which ought to be monitored with careful scrutiny. On the other hand, it is possible that the threat of such a powerful weapon will deter military conflict from coming to the fore altogether.
Live testing of the rail gun will commence in 2016.
