(Still a bad idea)
The person you're playing against might not though. Go play CoH:O. There's a hero rifle squad that starts with BARs and nades and a volks squad with mp40s and assault nades that you can build as your first unit. It's just not a good idea.
Impossible , if you made a unit with 5 LMG's not only would it be unbalanced but imaginary to other players , there is no way other players can see a unit since YOU are the one who made it on your comp. Its like the Skin bug where you can have different skins but only you see them.
OSTHEER IS DONE WHEN IT'S DONE!
