My son told me they issues "additions" to their body armour. Not sure what that means except hopefully more protection. He has never explained the insignia, but he is a squad leader
Thanks
welcome.
Additions likely means ceramic armor plates that go into the pouches internal to the vests.
Also there's work being done on kevlar arm covers and leg protection.
But that's still a bit away from practical combat use.
(The kevlar fabric tends to be bulky and stiff inhibiting movement to the point of being impractical in field use at the moment.)
