You sir, are wrong, I'm sorry, but your wrong.
I understand it's a lot easier to just cross you arms, stick out your chin and proclaim how wrong those who disagree with you are, but that doesn't prove a single thing. Just how am I wrong? Do guns magically teleport themselves to soldiers? Does artillery get up and walk to the most important front and use itself as needed? Do entire armies magically decide on how to fight and maneuver using the telepathic hivemind shared by all soldiers?
