Long-term field duty is not for sissy pants. Regular infantry would come back from a mission with hopes of getting hot meals and a shower when they arrive at base. Range-Vipers are different. Their barracks are not a four-sided building with a roof; it's out there on the cold, hard ground made of whatever makeshift materials they can find. Their meals are whatever edible walking or crawling critter that comes along, and their water comes from the nearest river or stream. They are only provided with their uniforms and basic weapons. Whatever else they need, they have to hunt for, scour, raid, and steal from enemy outposts. These men and women are recruited from the most extreme of wilderness enthusiasts with a propensity for violence.
