The Spearhead Lead Element (SLE), sometimes referred to as the Spearhead Land Element, is the principal high-readiness component of the British Armed Forces under the operational control of the Permanent Joint Headquarters. It is typically a battle group formed around a light infantry battalion, or Commando, with force elements from other arms allocated.
The SLE is oriented towards low and medium-intensity operations such as regional security, disaster-relief or non-combatant evacuation.
