But building the kinds of weapons the military wanted turned out to be much more difficult that everyone had figured (Nardo 27). hold ray guns would require too much power and would incur too hot.
They would also be too expensive to manufacture and at that price, ordinary rifles would be more effective. Then they started reservation big battlefield lasers to shoot mow enemy planes and satellites.
