There are a couple problems plaguing the use of laser weapons. First off, they take a ton of materials and power to properly shoot an effective laser and secondly, they are hindered by range. Lasers beams have no curve, leaving them to only be targeted within direct sight.
In comes the Tactical Relay Mirror System. This is a project being developed by the Office of Force Transformation. This system has been in the works for a few years now, and some early stage testing may finally become a reality. Giant mirrors would be places in the sky to act as a redirector for laser weapons. It is being speculated that these mirrors would be on blimps up in the sky.
