The Gnat-Swarm technique used by Vo Nguyen Giap was a style of fighting highlighted by mounting multiple small attacks on the enemy. Individually the battles meant little, but collectively they would weaken the enemy's resolve and confidence. By always being around and annoying, his soldiers were like a swarm of gnats.
The technique used by Vo was designed to irritate his opponents. The Gnat-Swarm technique was conducting many small battles a day, which in and of themselves were not overwhelming. The collective result , however, was reducing his enemy's desire to wage war, and go on the offensive. It reduced morale and kept the opponents guessing. They would swarm in and be annoying, like gnats.
Did Not contribute to the #13 or #14 questions and answers, but observed that the name "Nguyen" was used in some previous questions; wasn't clear, but believe the question asked "how was Nguyen used?" If this is a response to that same question, although it's apparently not asking how the name "Nguyen is being used", will submit just a little information anyway; just in case it does come up. The name "Nguyen" is equal to the American name of either "John" or "Smith." (In usage)
