  FRONTAL ASSAULT
  6-113. Afrontal assaultis a form of maneuver in which an attacking force seeks to destroy a weaker enemy
  force or fix a larger enemy force inplace over a broad front. The BCT commander uses a frontal assaultasa
  shaping operation in conjunction with other forms of maneuver. The commander employs a frontal assault
  to clear enemy security forces, overwhelm a depleted enemy during an exploitation or pursuit, and to fix
  enemy forces in place. The BCT commander conducts a frontal assaultwhen assailable flanks do not exist.
  While a penetration is a sharp attack designed to rupture the enemy position,the BCT commander designs a
  frontal assault to maintain continuous pressure along the entire front until either a breach occurs or the
  attacking forces succeed in forcing back the enemy. Frontal assaults conducted without overwhelming
  combat power areseldom decisive. (See figure 6-10.)
  6-114. A unit conducting a frontal assaultnormally has a wider area of operations than a unit conducting
  a penetration does. A commander conducting a frontal assault may not require any additional control
  measures beyond those established to control the overall mission. Control measures include an area of
  operations defined by unit boundaries,and an objective,at a minimum. The commander uses other control
  measures necessary to control the attack,including attack positions,lines of departure,PLs,assault positions,
  limits of advance, and direction of attack or axis of advance for every maneuver unit. (See FM 3-90-1 for
  additional information.)
