"Range Viper troopers are usually committed to long-term operations deep within unfriendly territory, completely cut off from communications or supplies. The have an unusually high tolerance for discomfort and can survive on a diet of grubs, roots, berries, nuts and whatever they can catch. They are expected to build their shelters out of indigenous materials such as rocks and mud, and procure their own ammunition by way of hit-and-run raids on enemy ammunition depots. They are favorites of Cobra Commander because they are so inexpensive to sustain. Once they're in the field, they don't cost anything to feed, clothe or arm."
