The U.S. Marine Corps adopted a similar system called Armor Protection Enhancement System (APES) around 2004-2005. This one was really uncomfortable and didn’t offer a really good protection. The Oklahoma State University (OSU) Design, Housing and Merchandizing Department led by D.H. Branson developed a full protection system that covers both arms and legs called Quadgard that quickly replaced the APES made by Point Blank Body Armor.
