Chapter 55-7. ATHPs are the most mobile and responsive of all ASAs. Each BCT and selected support brigadesare authorized an ATHP. It is located within the brigade support area (BSA) and is manned and operatedby the ATHP section of the BSB distribution company.

Field services provide quality of life for Soldiers. Field services are made up of six functions discussedbelow.Shower and Laundry5-9. Shower and laundry capabilities resident within the Field Services Company are provided from the SustBdes for supported units as far forward as possible. The mission is to provide Soldiers a minimum of oneweekly shower and up to 15 pounds of laundered clothing each week (comprising two uniform sets,undergarments, socks, and two towels). Shower and Laundry Clothing Repair Teams from the modularQuartermaster Field Services Company can be moved forward to provide field services for the BCT. Thelaundry and shower function does not include laundry decontamination support (see <strong>FM</strong> 3-11.5).5-2 <strong>FM</strong> 4-0 30 April 2009
Functions of <strong>Sustainment</strong>Food Preparation5-10. Food preparation is a basic unit function and one of the most important factors in Soldier health, morale,and welfare. Virtually every type of unit in the force structure has some <strong>org</strong>anic food service personnel.5-11. The field feeding system assumes use of Meals Ready to Eat (MREs) for the first several days followingdeployment, followed by transition to prepared group feeding rations. The theater initially transitions fromMREs to Unitized Group Rations. Then, as the operational situation permits, A-rations (fresh foods) areintroduced into theater. This requires extensive sustainment expansion since it requires refrigeration, storage,distribution, and ice making. The standard is to provide Soldiers at all echelons three quality meals per day.Proper refuse and waste disposal is important to avoid unit signature trails and maintain field sanitationstandards. See <strong>FM</strong> 4-20.2 for more details.Water Production and Distribution5-12. Water is an essential commodity. It is necessary for hydration, sanitation, food preparation, medicaltreatment, hygiene, construction, and decontamination. Support activities, such as helicopter maintenance, FP,and operation of medical facilities, consume large volumes of water. Classification of the water function issomewhat different from other commodities; it is both a field service and a supply function. Water purificationis a field service. Quartermaster supply units normally perform purification in conjunction with storage anddistribution of potable water which are supply functions. It is the users’ responsibility to determine potablewater requirements and submit them through supply channels.5-13. Water supply units perform routine testing. However, water quality monitoring is primarily theresponsibility of preventive medicine personnel of the MEDCOM (DS). The command surgeon ensures theperformance of tests associated with water source approval, monitoring and interpreting test results. Eachservice provides its own water resource support. Typically, the Army, as directed by the JFC, provides supportin a joint operation. AR 700-136 details the responsibilities of Army elements for water support.5-14. Engineers play a major role in providing water to Army forces. They are responsible for findingsubsurface water, drilling wells, and constructing, repairing, or maintaining water facilities. Geospatialengineers generate, manage, and analyze hydrologic data and work together with ground-survey teams andwell-drilling teams to locate water sources.5-15. The quantity of water required depends on the regional climate and the type and scope of operations.Temperate, tropic, and arctic environments normally have enough fresh surface and subsurface water sources tomeet raw water requirements for the force. In arid regions, providing water takes on significantly greaterdimensions. Soldiers must drink more water. Water requirements are significantly greater in areas, wheredemand is heavy for aircraft and vehicle washing, medical treatment, laundry and shower facilities, and whereconstruction projects are conducted.5-16. I/R operations may require a large amount of unanticipated bulk water consumption. Units must considerthe potential absence of water capability in enemy units and the requirement for on-site sanitation, shower,delousing, and medical support for in-coming detainees. Since water is a critical commodity in arid regions,managers must strictly control its use. Commanders must establish priorities.5-17. Because of the scarcity of potable water in some contingency areas, water support equipment may beprepositioned afloat. This allows initial support to a contingency force. Additional water equipment is availablein CONUS depots to sustain operations. Most of this equipment is packaged for tactical transportability. Itsconfiguration allows for throughput to the user with minimal handling in the AO.Clothing and Light Textile Repair5-18. Clean, serviceable clothing is essential for hygiene, discipline, and morale purposes. During peacetime,fixed facilities or field expedient methods normally provide clothing repair for short-duration exercises. Duringcombat operations, they are provided as far forward as the brigade area.5-19. Forces receive clothing support from a combination of units, HNS, and contractors. In low levels ofhostilities, HNS and contractors may provide much of this support. LOGCAP offers considerable capability30 April 2009 <strong>FM</strong> 4-0 5-3
