Does the Army wear bullet proof vest?

It's not a bulletproof vest. Its body armor and using different plates you are able to stop bullets from getting to vital areas. However the plates only cover the chest and back. There are smaller plates on the sides that protect underneath your arms. There is no such thing as a bullet proof vest. Now the body armor they wear does its job and saves many lives but not everyone will be saved. The vest do not protect your entire body from an explosion. And even though the body armor helps a lot a stray round can get into the chest cavity and wreak havoc on your internal organs.
