Producing lots of Infantry

No. Infantry is too slow. I would say build moto and mech inf, not plain inf.

It depends how you adversary does things, if he has tac bombers, artillery and tanks etc he could just harass your big slow stack of regular infantry until it's nothing more than a tiny slow stack of regular infantry. If your going mass infantry, as Bill said, use motorised or mechanised then they are faster and much more powerful.

Okay, thanks guys.

Its day 6 and I have 24 infantry and some more on the way. I will most likely research moto/mech as you guys recommended.

Build moto and mech, but remember they need oil, if you build up a sizable force it wI'll drain your oil supply along with tanks, ships, and planes, if you need more bodies to cover more land or add some little support invest on some inf IF you need to bridge the gap in terms of number.

Mechanized infantry is so boss at the max lvl.... The oil use isnt so bad, its less than a light tank.
