Laws of Battle
From Tardis Wiki, the free Doctor Who reference
The Laws of Battle was a code followed by the Sontaran Commander Kaagh. According to Kaagh, the first and second Laws of Battle were "Think like your enemy." and "Anticipate them." In addition, the third law was "Always have a Plan B." Alternatively, he identified "another rule of war", "infiltrate deep within your enemy, then infiltrate deeper still." (TV: The Last Sontaran)
