ORGANIZATI0N.-To provide a guide in the organization. training, and operation of units, the number, comPQsition, and equipment of operating teams have been outlined herein.

The organization of units and teams is shown wherever practicable by charts. These charts should be used as guides only. In operations. the available personnel and equipment should be so organized into teams as to meet the needs of the situation. Charts for cer tain teams indicate specialists required to provide a balanced team; otherwise, strengths are not indicated. • 3. EQUIPMENT AND SUPPLIEs.-T/BA 11 (Tables of Basic Allowances for Signal Corps) prescribe different allowances for peace and for mobilization (AR 310-60). Proper opera tion of units and teams described in this manual depends upon the availability at the time of mobilization of the au thorized allowance of their equipment and supplies. The 1 3-5 SIGNAL CORPS equipment and supplies peculiar to each unit are mentioned only to the extent considered necessary to indicate the oper ations of that unit. • 4. FORMATIONS, DRILLS, AND CEREMONIES.-The formations, drills, and ceremonies of all Signal Corps units covered in this manual are conducted in accordance with FM 22-5. • 5.
