Always honour a threat. The weight of all of your equipment is proportional to the cube of the time you have been carrying it. Hell hath no fury like a non-combatant. A lost battle is a battle one thinks one has lost. Surprise is an event that takes place in the mind of a commander.
All warfare is based on deception.
A little caution outflanks a large cavalry. No combat ready squad ever passed inspection. No inspection ready squad ever passed combat. Five second grenade fuses burn down in three seconds. The enemy diversion you are ignoring is the main attack.
