There are around 400 infantry battalions in the army.You want around 80 LMGs per battalion.Thats around 32,000 LMG.This will cater for half the requirement.
Indian army section firepower is not enough.Ghatak and para sf at least should have 2 LMGs per 8-10 men as well as 1 DMR.Fire team and assault team is based on old ww2 british and german tactics,maybe time to switch to newer fireteam concept of usa?
