  * Enough distance from other areas and units to preclude mutual interference.
  * Cover from direct fire.
  * Good drainage and soil conditions that can sustain unit vehicles and individual Soldier
  movements.
  * Terrain masking of electromagnetic signatures.
  * Terrain allowing observation of ground and air avenues into the assembly area.
  * A location beyond enemy medium artillery range.

  A-11. The proper location and size of assembly areas contributes significantly to both security and flexibility.
  The location should facilitate future operations, so movement to subsequent positions can take place smoothly
  and quickly by concealed routes. An assembly area must be large enough to accommodate the type and size
  of the force occupying it. Generally, dismounted infantry assembly areas are smaller than those assigned to
  armored or Stryker units. Because of their smaller signature, infantry units can use assembly areas closer to
  enemy forces than armored and Stryker units without excessive risk of enemy detection. The tactical mobility
  of armored and Stryker units allows them to occupy assembly areas at a greater distance from the LD than
  infantry units.
  A-12. There are three methods to organize an assembly area: as a single area, as part of a large assembly area,
  or dispersed. The biggest difference between the three methods is the amount of security required since every
  assembly area inherently conducts a perimeter defense. See Figures A-4, A-5, and A-6 for examples of each
  method.
  A-13. The single area method configures a unit in a perimeter defense with maneuver units deployed along
  the entire perimeter. Command and control, sustainment, and any other supporting units are located within
  the interior of the assembly area. Figure A-4 is an example of a single area assembly area for a battalion task
  force.
