Center Body Mass. the area of the body above the belt line and below the collar bone. the preferred target area of police forces and army personnel alike. head-shots are unrealistic in small arms combat. armies and law enforcement agencies worldwide are trained to aim for this region as it is the biggest section of the body and houses plenty of vital organs.
when aiming for the CBM you have a better chance of disabling your target permanently as the bullets will likely hit vital organs (ie. heart, lungs, liver, kidneys, spine)
