  Figure 2-19. Infiltration
  2-83. Units conduct infiltration to move all or a portion of a unit through gaps in the enemy force’s defenses
  to—
  * Reconnoiter known or templated enemy positions and conduct surveillance of named areas of
  interest and targeted areas of interest.
  * Attack enemy-held positions from an unexpected direction.
  * Occupy a support by fire position to support the main effort.
  * Secure key terrain.
  * Conduct ambushes and raids to destroy vital facilities and disrupt the enemy force’s defensive
  structure by attacking enemy reserves, fire support and air defense systems, communications
  nodes, and sustainment elements.
  * Conduct a covert breach of an obstacle or obstacle complex.
  2-84. Special operations forces and dismounted infantry units up to brigade size are best suited to conduct
  an infiltration. In some circumstances, armored- and Stryker-equipped forces operating in small units can
  conduct an infiltration when the terrain can mask their force’s movement signature. The proliferation of
  technology leads to increased situational understanding for both friendly and enemy forces as well as an
  increased chance of detecting units conducting an infiltration. Understanding the capabilities of these
  technologies informs the decision as to whether an infiltration is feasible.
