Previous: 3-62: Primary Position

3-63. Alternate positions are those assigned when the primary position becomes untenable or unsuitable for carrying out the assigned task. (See figure 3-7.) These positions allow the defender to carry out his original task. The following considerations apply for an alternate battle position:

• It covers the same avenue of approach or sector of fire as the primary battle position.
• It is located slightly to the front, flank, or rear of the primary battle position.
• It may be positioned forward of the primary battle position during limited visibility operations.
• It is employed to supplement or support positions with weapons of limited range, such as dismounted positions.
