Sgt Seavers of the Orphan Corps is having a run of bad luck. First, he gets in a fight with three marines while on a space station. Second, he wins that fight. And now, after learning he was being considered for officer candidate training, he is informed of his penance.

Can Seavers handle a resentful platoon of Marines? Can he do it while delivering medical aid to a suspicious colony of terraformers?

To get back his chance at officer candidate training, he'll do his best. Or die trying.

If you love a good military adventure crossed with sci-fi worthy of Andre Norton and Asimov, then Rescue on Gimhae is the story you're looking for.
