Five by Five 3: Target Zone. Five by Five, #3

Five short novels by five masters of military SF capture the excitement, and hell, of fantastic future war-on and off the battlefield. Stories of terrifying monsters, dangerous aliens and staggering cosmic dreadnaughts march alongside far-flung courtroom dramas and cautionary tales involving man and his devices. Michael A. Stackpole-The Star Tigers are commandeered by a powerful alien overseer on a covert mission to a world long abandoned by an ancient species.
There, the ruins of a forgotten war will tip the balance of their war, unless the Star Tigers can prevent it. Sarah A. Hoyt-Lucius Dante Maximilian Keeva is a well-respected leader of the Usaian Revolution, but treason in the ranks can cost him everything that makes life worth living-unless he takes justice into his own hands and breaks every military regulation in its pursuit. Doug Dandridge-Faced with an enemy more than two hundred times her own size, Cinda Klerk has two options: hide, and let it destroy the planet she is supposed to protect, or find a way to even the odds and kill the enemy, even at the cost of her ship and crew.
Eytan Kollin and Dani Kollin-As the Unincorporated War envelops the entire solar system, a father must come to the rescue of a daughter he never raised. But he'll have to convince her to save herself first. Kevin J. Anderson-In the war against an alien menace, Earth's greatest military commanders risk themselves on the front lines, but with an escape hatch: If the situation goes terribly wrong, they can switch places with a safe soldier far from the battlefield.
But the cannon-fodder volunteers don't consider that such a good deal. Set your cross-hairs on the Target Zone.
