While I agree that there is a massive overuse of bandages (I'm looking at all you spec ops players) at the individual level, I still think there is a major problem with the LAT kit.
One LAT is not what a squad would be issued, nor is it enough to be a tactical asset within PR. At this point, it's an emergency tool, or only used against infantry, because there is simply no way to effectively engage light armor with it.
The M136 AT4 is a recoilless rifle used primarily by Infantry Forces for engagement and defeat of light armor.

Clearly, the AT4 is not being deployed realistically in PR. I think this needs to be addressed. I don't think the entire ammo system needs a rehaul, I do however think that some specific things need to be rethought: LAT rockets,
possibly HAT rounds, and probably smoke grenades, which are not an offensive weapon and really shouldn't be taking up a whole lot of ammo.
I can't really offer an effective way to implement these changes, because I have no clue how the ammo system works. If someone could enlighten me, I'd gladly help brainstorm, but until then I'm stuck.
