These types of targets are very useful for target or threat identification.
LE Targets offers (may include) sets of cover up hands to paste onto these types of targets. Some cover up hands are empty, holding cell phones, grenades, etc to yield almost limitless variations.
Much better to train a guy to shoot an appropriate threat than to shoot only sillohuettes and hope for the best when he is under stress, would you not agree?
God gave you a soul.
Your parents, a body.
Your country, a rifle.
Keep all of them clean.
