carbineer

noun

1. A soldier armed with a carbine.

   “The prisoner flung him off with a force scarcely to be expected from one of his slight figure, and, turning quickly, said, "Let me die like a man!—whatever is my death, let me face it!" No further effort was made to blindfold him; but the carbineers formed their deadly rank, looking, however, towards their commander for the signal.”
