This was important not only from thestandpoint of helmet production, but from the fur-ther inference that body armor of such steel mighstill be profitably used. The records of the hospitals in France show that 7 or 8 of every 10wounded soldiers were wounded by fragmentsshell and other missiles which even thin arrplate would have kept out.
