The Highcom 3S9 is a remarkably tough but lightweight level III+ composite plate but the Army's new enhanced performance round has shown impressive penetration abilities in both 5.56mm flavor and now in 7.62x51mm flavor. M80A1 was able to perforate the Amour Wear "AR680 LVL 3+" plate and the Spartan 3610 GL level III+ composite plate. The 3S9 is also level III+, but it is thicker, slightly heavier, and presumably tougher than the Spartan 3610GL. Place yer bets.
