And where is US of America in this list! They are seriously considering next gen rounds and working prototypes have already been built and marketed by the competing companies. Russia and China is doing the same behind the closely knit curtains as usual. Everyone else would have to eventually follow their footsteps.
If you think Pakistan has the economy strong enough to induct and mass produce SCAR-H now and after one and a half decade later when next Gen rifles would flood the market, go for another shopping spree for upto date rifles and their associated calibers? I don't think so!
IMHO if we induct our standard issue rifle now, we wouldn't be able to induct a new standard issue rifle at least before 2060 or maybe beyond that. And in 2060s maybe the rounds we use now would have no more effect on the armored soldiers of that time than the Palestinian kids launching stones against the occupying forces today! That should be a huge concern for all of us.
