A unit of exceptionally talented native troops, expert night fighters and hand to hand sentry killers, is dismissed from the battle lines. They have a reputation for leaving their long arms behind and just taking a long, bent knife with them to go into the no-man's land between forces to search for enemy patrols and snipers as well as spotters. They either don't come back or come back with a string of ears. The ears start to stink and gross out some upper echelons with squeamish stomachs, so the unit is rotated out of this theater.
