Appendix N 370 ATP 5-0.2-1 07 December 2020 Table N-5. Supply considerations in extreme environments (continued) Class Environment Considerations CL V Cold weather- specific Expect an increase in requirements for aerial rockets and tactical air support due to the limited mobility of ground artillery. Consider multiple cache or resupply via helicopter for forward units. Mines often fail to explode when stepped on or when driven over by heavy equipment. The slower burning rates for propellants may reduce the maximum effective ranges for artillery by as much as a kilometer. Initial rounds fired from cold tubes also have reduced range. Due to the dampening effect of deep snow or mud, impact bursts of artillery and mortars are less effective (by as much as 80 percent). Use of a variable time fuse can help overcome this; however, a potential increase in fuse failure exists at 0 degrees Fahrenheit, in heavy rain, and in snow. Phosphorus shells produce obscurant; however, they can contaminate the area of impact with particles. Extreme cold decreases muzzle velocity and hence the accuracy of tank ammunition. CL VI Desert and arid environments The demand for Class VI supplies, especially beverages, is high. They are not, however, essential, and, if transportation is limited, they are given a low priority—especially if refrigeration space is in short supply. Sundries packs can also be used. Mountain See cold weather. Cold weather- specific An increased need for health and comfort packages may be present during mountainous operations. Plan in advance for specific items needed for the environment. CL VII Desert and arid environments The demand for Class VII supplies depends greatly on maneuver and the intensity of the operation. The only variation that can be forecast is for refrigeration equipment, which depends on casualty estimates. Mountain Resupply of battle-damaged major end items is a significant challenge in mountain operations. Movement of deadline equipment clogs narrow supply routes. Forward-based units that stay lean may not be able to stock many spare end items. When equipment is destroyed or damaged beyond repair, the only course of action (COA) is redistribution. Cold weather- specific Cold weather increases demand for power generators, heaters, and rough terrain loaders with snow removal capability. The demand for other clearing vehicles and attachments for snow removal also increases. CL VIII Desert and arid environments Heat can damage some CL VIII supplies and cause reduction in the shelf life of others. Care should be taken when transporting CL VIII supplies into theater to maintain temperature variables. Mountain See cold weather. Cold weather- specific High consumption rates for medical supplies should be anticipated. Move CL VIII supplies by air whenever possible. Normally medical items require heated transportation since they are particularly susceptible to damage from freezing. Some items that are particularly vulnerable to cold are— • Oxygen or compressed air tanks. • Surgical sinks. • X-ray machines. • Combat lifesaver bag contents. • Medications, intravenous solutions, and, especially, whole blood.
