Training at the speed of life, volume one

In violent, desperate times, we are training as hard and fast as is safely possible. We walk a fine line, training to survive; training to save the infinitely precious lives of warriors and innocents locked in mortal combat. But we must conduct that training so we will never take those infinitely precious lives through training accidents. This book serves as the definitive map to guide us along that fine line, the most powerful and vital of all lines; the line between life and death.
