The Legionnaires

In this short story by T. C. McCarthy, one ordinary woman with nothing to lose joins the French Foreign Legion and finds herself, and her comrades, pinned down in a bunker surrounded by enemies. Thousands of the mantis-like creatures swarm towards them and with no communications and little ammo, survival is a desperate hope. She is a volunteer and a soldier, and to save herself, her squad, and the refugees they defend, she must remember the life she left behind.
