Brilliant Lances (1993)

From the Box:
In space combat, you never see your opponent until it's all over, if even then. With acquisition and tracking ranges measured in tens of thousands of kilometers, to human eyes the people that are trying to kill you are not even a speck. But they can hurt you, even though you can't see them. Precise laster arrays and big particle accelerators, honed by centuries of engineering, can reach out without warning to slit your hull like the belly of a fish, spilling life--oxygen, heat, and fuel--into the hard vacuum. That's why space combat is a game of cat and mouse. Keep yourself wrapped in the mantle of space--cold, dark, silent. Keep your thrust burns to a minimum--they blaze like miniature suns for all to detect. Rig your passive sensors to greedily absorb data, but remain quiet yourself--give nothing away. Keep your weapons ready, in case… There! A faint trace of mid-wavelength infrared betrays a meneuver drive. Bring up the ladar dishes while the big passive array builds up a targeting solution. The moments seem endless while every crewmember shares the same thought: "Have they seen us?" It is the unseen enemy at this moment doing the same thing that you are? You might never know the answer. If you beat him, maybe you'll find out. But what if you hadn't seen him first? Some questions must remain unasnwered when death, unbidden, comes scorching toward you as silent, brilliant lances.
