All parts - Range-Viper

Backpack - Hardball (modified)
Grenade launcher - Range-Viper
Machine gun - Marauder Inc.
Knife - Shockwave

Cobra Range-Vipers must have an awful time being stealthy in the wilderness. With a fairly bright blue being their primary colour, they're not exactly camouflaged. So this custom is simply to give the Range-Viper a more appropriate uniform for its role. I also altered the accessories a bit, using Hardball's backpack to still have plenty of ammo for the grenade launcher, but also adding a machine gun to explain the ammo belts that Range-Vipers carry.
