Army recalls helmets after test failure

Are you reading what I'm reading? I just want to make sure I'm reading this right. How is it possible they know for a fact "no soldiers or airmen" have been injured if they don't have a clue how many of these helmet were even worn in combat?

No soldiers or airmen have been injured as a result of the defect, Army officials said. They don’t know how many of the helmets have been worn into combat, they said, but about 30,000 of them have been issued to soldiers and airmen.

Next question is how can they be sure no soldier or airmen had their brains injured by these defective helmets? If they have a weak spot then isn't that possible?

The Army has recalled about 30,000 of its Advanced Combat Helmets after a manufacture’s defect caused the helmets to fail ballistic testing.

The helmets issued to soldiers and Air Force personnel from November 2008 to February 2009 are the subject of an investigation by Army Criminal Investigation Command.

Gentex Corp. of Carbondale, Penn., was “supposed to provide a particular product and they provided something different,” Lt. Col. Robert Myles, product manager for Soldier Survivability, told Army Times April 30.

Gentex notified the Army in January that one of its subcontractors used “a different finish on the screws than what is required by the government,” Myles said. The finish is designed to protect the screws from corrosion.

The former subcontractor, A.J. Hughes Screw Products Company Inc., is under investigation by Army CID and Gentex is not, said Ken Lee, corporate counsel for Gentex.
