The item I most miss is an effective Quad. 4x.50 cal out to rip light armor to pieces and present a really good Anti-inf unit. Instead it is a a glass water pistol that can't suppress. Is it any good against PE armor?
It rips all PE light vehicles to shreds and is good at suppressing panzergrenadiers. That said, for US v. PE I almost always use Aimstrong's anti-PE strategy. Inverse made a good video explaining the strategy: http://www.youtube.com/watch?v=DSz5-ym_Qg4
If you want to talk US v. PE, however, you should probably start another thread so this one doesn't go crazily off-topic.
