As stated in Field Manual 100-1, "The Army," it is the Army's fundamental purpose to win wars through land force dominance regardless of location or climate. This Field Manual provides general doctrinal and technical guidance for operating equipment and ordnance materiel under extremely harsh cold weather conditions. Its primary purpose is to familiarize operators and crews with the special procedures and techniques for working in sub-zero temperatures. Also, this manual will assist unit commanders, supervisors (motor sergeants, battalion motor officers), and maintenance personnel in anticipating and planning for the onset of cold weather or an arctic deployment. Failure to follow this guidance can cause injury to personnel and damage to equipment, besides limiting mission accomplishment.
