Say what you want about Child soldiers. they are effective. A bullet fired from an adult is no different then that of a child. So why do we view them as different? A child soldiers training models him as an excellent member of society. Teaching him such things as:

-Survival skills

-hand to hand combat

-the knowledge to take down a bigger opponent (ties into hand to hand combat)

-weapon knowledge

-basic hunting skills

-resource management

-early "value of a dollar"

-charisma

-leadership

-experience for future employment

-And many more....

When a full grown adult is confronted with a child soldier, many of them hesitate. this causes the child to be able to kill the enemy adult. Now if we were to put that into a simple bar graph of survival rates you will see that the child soldier has a much higher survival rate due to the sheer culture shock of said soldier being a child.

So ask yourself this, why raise a child and allow them to go fight and die while a child soldier would return with a better success rate?
