Ammo limits

[Listy]

I've been looking at LAW weapons and their ammo amounts.

It seems that most infantry squads are carrying absolutely staggering amounts of Ammo; some squads are carrying one LAW per man, including MG crews!

Now I'm wondering if this is based around game balance. Because in my earlier mod for the UK, I found that putting the correct amount of ammo in the section (IE: 2 LAWs per section) tended to make life very difficult when facing an armour charge.

So what I'm asking is there a reason for this? Or is it something done for game balance and explained away by saying the unit is getting low levels of resupply, or some such?
