Scifi war stories have always entertained me when they get technical and concise with their technology. It's not required but it definitely helps one understand the technology and the limitations there of. Its a fine line that separates scifi from technofantasy where technology is magical in the sense that it does whatever the plot requires it to. In comes the Lost Fleet, a series of novels written by Jack Campbell. It takes known problems with any kind of large scale space battle and mixes them with scifi technology in his war story. Examples would be time delays in instructions due to the speed of light, space starfighters being almost non existent due to weak mass to thrust ratios in the vacuum of space, the amount of training it takes to produce an officer able to manage the basics of 4 dimensional battle tactics, orbital bombardments via large kinetic projectiles, and three dimensional movement for all ships. What it lacks in careful character storywriting or larger themes, it makes up for in careful execution of various known concepts of physics mixed with imagined technologies. If you want a story that handles conflicts in space well and entertainingly, Lost Fleet might be for you.
