>Okay but whats the different between pic and an assault rifle?
It weighs like a motherfucker and requires at least 2 people to carry. They tried to solve the issue with lighter machineguns like Lewis gun which people could bring to assaults. In WW2 they further split the gun types to machineguns and SMGs like Thompsons you see in gangster films. Eventually armies settled to assault rifles because they combined the accuracy of rifles with the firepower of SMGs. SMGs were always useful in urban combat so armies haven't fully gotten rid of them.
