But still, we (the US (I live there)) have experimental DEW systems. As I stated: in 500 years, DEWs will be cheaper and easier to power (they have fusion packs on soldiers).

And tactics in war are always changing. Weapons are always changing. The US went against traditional warefare when the revolution happened, attacking from the bushes.

The one who fallows "traditional tactics" and the "rules of war" usually lose.
