The U.S. Army awarded the University of Southern Missisisippi a $4.9 million grant to conduct research into helmet liners for soldiers.

Army leaders want researchers at the university to develop a new pneumatic cushioning system to better protect soldiers and hopefully design a more comfortable helmet.

The school has worked with Rawlings Sporting Goods — makers of baseball and football helmets — since 2011 to help produce liners for football helmets.
