with these aks and with so many high profile people around i don't think they will hit anything other than friendlies,it is a fking 7.62 round for heaven sake,as JC demonstrated in one of his documentaries (starts @1:32)
The helmet was a standard issue in Pak army as well till 2007 when pak realized that it was shit and too heavy in a modern war and replaced with new gen modular polymer helmets,which is light weight+more ballistic protection,india tho still uses similar ww2 helmets.
If i was to decide equipment for bd commandos i would have chosen better helmets over cool looking eyewear,bd commandos i don't doubt are well trained but not well equipped(and dressed).Just a humble opinion,don't cock your guns right away.
Some cheaper equipment which can make a whole lot a difference.
A better digital camouflage pattern wala uniform,use of carbine/bullpup instead of a battle rifle,polymer helmet,lvl 3 kevlar jackets,newer grippy DMS.
m4 carbine or even ak47u type can be purchased for pretty low price
Kris vector and uzi are pretty much useless.
Mp5 or mp7 are better.
