Within this process the logistician finds himself embattled in the ultimate test of his skills. Specifically, he must first concentrate on strategic mobility and then sustained operations ashore. With the advent of Maritime Pre-Positioning Ships, concepts are being developed to solve the strategic mobility problems of the logistician. Sus- tained operations, on the other hand, though complicated would not appear to be a logistical problem. After all, the Marine Corps has conducted hundreds of training operations involving amphibious operations from which sound concepts of operations and doctrine have evolved. Unfortunately, this is not the case. The U.S. Marine Corps, with forces designated for Supreme Allied Command Europe's Strategic Reserve has found itself in a role in which it has a requirement to be ready to fight in the cold- weather environment of the Northern Flank region of NATO. In this type environment, the logistician will be confronted with support problems that have not totally evolved into a bear concept of support for sustained operations ashore. Recent recommendations from units conducting cold weather operations in Norway have included that future train- ing operations should not exceed the size of a Marine Amphi- bious Unit. This is interesting in light of the fact that a civilian reporter, Hanson Baldwin, had made a similar observa- tion in the 8 February 1947 issue of the New York Times. After accompanying the 82nd Airborne which was conducting exhaustive cold weather testing in upper New York State, Mr. Hanson wrote that "arctic airborne operations, or arctic operations of a conventional force larger than a battalion are well nigh im- possible."1 In both these instances, the conclusions were based on the problems inherent to logistical support. At first glance, you might conclude that little has been done in 37 years to solve logistical problems that are as- sociated with a cold weather environment. This is not necessarily true. Since the Marine Corps received its com- mitment to assist in the defense or Norway, an incredible effort has been made to properly train and equip Marines to fight in a cold-weather environment. Since 1976, cold weather initiatives include conducting numerous training exercises in Norway, reopening of the Mountain Warfare Train- ing Center, establishing a working group to oversee the development of cold-weather related equipment, incorporating standards for cold-weather operations as part of the Marine Corps Combat Readiness Evaluation System (MCCRES), designating a centralized cold-weather coordinating authority at Head- quarters, U.S. Marine Corps, and commissioning a private concern to conduct a comprehensive, independent cold weather combat operations study. As a result of the various recommendations that have emanated from cold weather after action reports, conferences and the independent study, numerous improvements to combat service support equipment have been adopted by the Marine Corps. However, Marine logisticians must recognize that new equipment is not the panacea to success in cold weather opera- tions. Major changes to the concept of combat service support must be made by the Marine Corps if timely and effective sustained support of infantry units is to be accomplished in a cold weather environment. One possible scenario that may be considered in order to develop a concept of combat service support and to assist in the identification of changes that must be made would be the isolation of northern Norway by Soviet forces during the winter months. A Marine Amphibious Force may have to be landed into southern Norway in the vicinity of Hague and at the airfield at Lista with a mission to attack north to seize the port city of Stavanger and the airfields at Sola-Forus. In this particular case, a warm weather landing would entail the classic amphibious landing with waves of amphi- bious tractors followed by landing craft. Since this scenario assumes the threat to be in North Norway, the landing would be relatively unopposed. The off loading of assault echelon supplies would continue through D+5 with the Assault Follow- On Echelon (AFOE) arriving thereafter. As the MAF is moving north they would be supported by regimental trains which would be initially resupplied from the Force Combat Service Support Area (FCSSA) which is rapidly developing at Hague. As the operation progresses, a forward combat service sup- port area would probably be established in the vicinity of Naebro to support the final phase of the assault on Stavanger. A closer look at this same scenario in cold weather will result in major considerations by the logistician and changes to the concept of combat service support. These major con- siderations and changes will focus on the landing, the time required to build the Force Combat Service Support Area (FCSSA), composition of regimental trains, mobility, resupply, and maintenance procedures. With regard to the landing, the Landing Vehicles Tracked (LVT) will have extreme difficulty getting off the beach if there is more than thirty inches of snow on the ground.2 This very problem was incurred by the 36th MAU during Coldex 81. In this case, Marines were landed in landing craft to secure the beach while Norwegian bulldozers were used to clear a path so the LVTs could land.3 This particular problem calls for a complete change to the Marine Corps' embarkation phase of combat service support since we cannot count on indigenious personnel to be on hand with snow removal equipment. Bulldozers will have to be loaded so as to be in the 1st or 2nd wave. Moreover, planners must be able to tap additional resources from the Naval Con- struction Battalion to ensure that the landing force has adequate assets. This problem also affects the operational planner since the initial assault waves will have to be landed in naval landing craft vice amphibious tractors. The next major consideration will be the build-up of supplies and equipment on the beach and the establishment of the Force Combat Service Support Area. During a warm weather operation, this responsibility is a very tedious, strenuous phase of the operation because of the heavy work involved in off-loading the ships and positioning supplies and equipment by functional area. Marines assigned to the Landing Force Support Party know that this is a critical phase of the con- bat operation because major resupply of the units pressing on Stavanger will be required. In a cold weather operation, there are three major considerations which the logistician is going to have to consider during the buildup of the FCSSA: time, fatigue, and wet troops. Since 1976, every after-action report and in-depth study on cold weather operations have addressed the fact that it takes 3 times longer to perform normal tasks in cold weather. Since this factor also affects infantry units, there should be no problem with the time to build up supplies since infantry operations are going to be slowed down accordingly. However, there will be a problem with being ready to off-load the Assault Follow-On Echelon at D+5. This will probably have to be moved back to a mini- mum of D+10 unless the Landing Force Support Party is aug- mented with additional personnel from the Division and Wing units. This augmentation appears even more of a feasible consideration when considering fatigue and wet troops as a factor. With regard to fatigue and wet troops, there seems to be a universal acceptance that a fully trained and physically conditioned Marine does not function effectively for the initial several days when he is displaced from a warmer cli- mate to a cold environment. It is also reasonable to expect that as in warm weather landings, those Marines working in the Beach Support Area will get wet during the performance of off-loading vehicles and supplies from the landing craft. In a cold weather operation, this will result in numerous cold weather injuries if these Marines are permitted to oper- ate under these conditions for very long. Currently, there is only one alternative to this problem. The troops will have to be evacuated to the ships where they can get warm, eat a warm meal,and have their wet clothes dried in the ships laundry. Warming tents may be used on the beach but they will not serve to dry the heavy arctic clothing. This pro- cedure will require platooning the LFSP into working parties. This requires another change to the concept of combat service support for the Landing Force Support Party. The Marine Corps has not really addressed this problem in any detail; however, they have introduced plans for a new combined laundry and bath unit (CLABU).4 It will not be capable of handling insulated winter clothing; therefore, planning factors for front line troops must include evacuation of arctic insulated clothing back to the FCSSA for cleaning by the bulk laundry units of the Force Service Support Group. This exchange of outer clothing is mandatory since the insu- lation properties in the arctic clothing will become less effective as they are soiled.5 From this fact, it becomes obvious that the composition of regimental supply trains may be taking on an added dimen- sion. Normally, these trains consisting primarily of 5 ton prime movers will follow the assault echelons within 15 kilometers and consist of 45-50 trucks. They will primarily be carrying three classes of supply: subsistence, petroleum, and ammunition. Henceforth, these trains must be capable of carrying a change of arctic clothing for the entire regiment. Moreover, planning factors must include a change of inner garments but not necessarily on a 1 to 1 ratio since introduction of the CLABU will alleviate the cleaning problem for undergarments of the assault regiments. The CLABU unit will be helicopter transportable thus a concept of combat service support should include this as the primary means of transportation since regimental trains will be swelling in size as a result of the additional cold weather clothing. The primary consideration the logistician will have to keep in mind is that under normal winter conditions, 65 to 70 pounds is the maximum weight a man can normally wear and carry.6 Since 45 to 55 pounds of clothing and equipment is required for protection and comfort of each Marine under con- ditions of extreme cold, his basic load of food and ammunition will have to be reduced.7 In order to accomplish this re- duction, regimental trains will again be taxed. We are pro- bably looking at an additional 25 trucks for each train,thus a new problem surfaces that has not been resolved. The additional trucks required in the regimental trains are going to have to come from somewhere. Should the Marine Corps configure its Force Service Support Group to provide this added requirement? Should critical resupply be air dependent in light of weather and threat constraints? If the decision is to go with what we have, do we strip the FCSSA of its assets or do we decrease the mobility of the reserves? These questions must be answered now before the MAF logisticians can refine their concept of combat service support. Assuming the problem of regimental trains can be re- solved with regards to their composition, the planner must now consider their mobility and the means by which battalions will be able to effect the actual resupply of the front line units. The problem of mobility begins back at the beach. If as stated with the amphibians, there is more than 30 inches or snow, the off-loading of the 5 ton trucks will be difficult at best. The LFSP will have to ensure a marshalling area is established for the purpose of placing cleated, highly durable tire chains on all wheeled vehicles. This, of course, re- quires a dedicated work force. This additional marshalling area and work force will constitute an additional change to established combat service support concepts for beach opera- tions. Also within this marshalling area selected 5 ton vehicles will have to be equipped with commercial snowplow attachments. The new 5 ton series trucks being purchased by the Marine Corps will be compatible for such attachments so previous expedients such as engineer motorized graders, bull- dozers and bucket loaders will not have to be relied on for the sole source of snow removal as the operation progresses north.8 Since snow removal equates to mobility, this aspect of combat service support must receive optimum attention during the detailed,parallel, and concurrent planning with the operational planners. In this regard, it would appear feas- ible for the logistician to develop a new appendix to the Combat Service Support Annex of the Operation Plan. This annex must identify vehicles to be used with dedicated, trained drivers. Moreover, the appendix should also break down the operation into three phases: clearing and mainten- ance of the Main Supply Route (MSR), expeditionary airfields and landing zones, and FCSSA and forward CSSAs. The main assault regiments will have to place their snow removal trucks well forward. In this regard, it is not en- visioned that more than 4 plow configured trucks will be needed with the lead elements because of the narrow MSRs in Norway. Since economy of space is important due to the limited number of trucks available to support the logistics trains, these vehicles will also have to be loaded with re- supply items. It will also be important to consider the types of supplies that will be transported by these vehicles. For instance, it would be unsound planning to have petroleum or ammunition carried in these vehicles. The regimental trains, on the other hand, though they will be up to 15 kilometers behind the lead battalions, must be equipped with as many plows as economically feasible. There are three primary reasons for this. First, the primary MSR, which in this scenario will be Route 40, will be com- pacted by continous heavy traffic. This will cause a rapid melt situation which will make trafficability for the regi- mental trains extremely difficult. Secondly, the plows may be needed to bear helicopter landing zones for resupply of the trains. Finally, an adequate quantity will be needed at Naebro to begin clearing operations for the forward Combat Service Support Area. Failure to plan accordingly will most certainly slow the advance of the assault echelons. Resupply in this scenario requires an additional con- sideration. Though a change in concept of support is not required, there is one major consideration which must be given weight by the logistical planner. Under normal weather con- ditions, forward battalions would be resupplied by sending prime movers back to the trains or a midway rendezvous point. The regimental trains would more than likely be resupplied by helicopter. This procedure may still be used; however, front line units must now consider the use of the BV202 Over Snow Vehicle. Depending on the actual distance and location of the units from the regimental trains, it may be more econo- mical to send these vehicles directly to the regimental trains instead of using organic prime movers. If adequate resupply can be accomplished in this manner, this procedure may also serve to help keep the main MSR from being overly congested with vehicle traffic. One final consideration that is going to result in a major change to the concept of combat service support lies in the area of maintenance. As in a warm weather campaign, suc- cess of the mission is going to depend heavily on the avail- ability of weapons and equipment. This means continual support. Maintenance problems will be more difficult to correct in cold weather because of the restricted use of con- tact teams. Current doctrine relies heavily on contact teams moving forward to perform corrective maintenance; how- ever, this use of contact teams in cold weather will not be feasible for two reasons: reduction of spare parts in the regimental trains and lack of a mobile heated facility to perform the maintenance. One possible alternative to this problem would be the establishment of a forward contact team work area midway be- tween the FCSSA and the proposed CSSA at Naebro and then mid- way between the CSSA at Naebro and the final objective at Stavanger. This procedure, though not totally satisfactory, would reduce the distance equipment would have to be evacu- ated. Also, it would be most beneficial in cases where prime movers would be evacuating heavy equipment on 40 ton lowboy trailers since it will reduce diesel consumption. The contact team work area would have to employ the use of the new Marine Corps Expeditionary Shelter System.9 In addition to this shelter and maintenance personnel, dedicated heavy equipment operators and drivers must be available to evacuate equipment from the assault regiments to this area and, if required, back to the FCSSA. Regardless of future recommendations and improvements to specific equipment categories for the cold weather environ- ment, the Marine Corps must formulate specific concepts of combat service support for their application. The individual Marine has a high degree of "esprit de Corps" and has proven to be innovative in the worst of conditions; however, cold weather combat operations is not the place for innovation. Failure to get off the beach because of snow trafficability problems could recreate the casualties amassed during the seizure of Tarawa in WWII,where it was the coral reefs and not snow, that stopped the amphibians. As in any amphibious operation, a steady flow of supplies from the FCSSA to the lead regiments can only be accomplished by a continous con- certed effort by support personnel. This is going to require special attention to the effects of the cold weather on their ability to work around the clock. The composition of our logistics trains is going to re- quire an evolution in doctrine that parallels the same inten- sive effort that was used to develop the embarkation phase of the amphibious operation. Getting the right supplies in sufficient quantity to our combat troops at the proper time is the very essence of combat service support. Finally, snow removal operations is nothing to be taken for granted and requires dedicated planning. This phase of cold weather operations could very well prove to be the Marine Corps' Achilles' heel!
