[Suggestion] Armour piercing rounds for infantry weapons

You need resources for those things, they are not "unlimited."

True, but even with numerous options that infantry have, the only way to actually be effective is in a coordinated assault. Where as 1 tank can take out an entire squad on it's own.

"Over the top" you say? What do you expect, for infantry to just roll over and take a pounding from tanks and for it to be status quo?
