I know that Croatian anti material rifle was also mentioned in some topics and thats ofcourse the RT-20 but there is version called RT-21 that is improved. The data on wikipedia are kinda obsolete... I hope you will agree with me that Croatia has currently the best assault rifle and helmet and the best sniper rifle to penetrate most armored vehicles. It can easily kill Bradley from 1 or 2 km.
