He could've called it Operational Warfare, that'd be the same.
And anyway, that's what he calls them, Raids. Military tactics missions.
Purposes of Raids:
  • to demoralize, confuse, or exhaust an enemy
  • to ransack or pillage a location
  • to obtain property or capture people
  • to destroy goods or other things with an economic value
  • to free POWs
  • to kill or capture specific people
  • to gather intelligence.
And thank Wikipedia for their informations.
