The Marine Corps' top general says America's way of warfighting has adapted from organized warfare with clear lines, to a chaotic multi-dimensional battlefield that not only has no front lines, but also has expanded into cyberspace and information technology

Speaking Tuesday at the Center for Strategic and International Studies, Marine Commandant Gen. Robert Neller said, "The fight that we used to think about, you know air land and sea, and under the sea, is now expanded to space, to cyber and the information domain."

Neller cited Monday's shutdown of Delta Airlines operations by a computer glitch as an example of how vulnerable Internet-based computer networks are to cyberattacks.

"Look what happened with Delta," Neller said. "They build an entire system of reservations and flight management based on this network, and it failed, just by itself, because of the power surge, but what if somebody actually wanted to do that?"

Neller credits the U.S. military in general and Marines in particular for adapting their doctrine to the changing world.

Neller is fond of explaining the change in American military thinking in sports terms.

"We like football," Neller said. "The field is all lined out, goals on either and, referees all around the field to make sure people play by the rules. We like that. And then you would stop to call a play and make another play."

But Neller notes the American style of football is not how the rest of the world plays the game.

"The rest of the world likes soccer. There is one referee who never seems to see anything, guys run around in different directions all the times, they fall down even though they are not touched, we think that's bad, but everybody else just thinks that's part of the game. In military, that's called deception."

Neller says the Marine Corps brings unique capability to the fight because of its expeditionary mission.

"To me that means when you show up, you have to be able to bring with you all the things that you need to sustain yourself for at least a certain period of time before you can get a logistical chain to support your efforts," Neller said.

"And then none of the games we play, hopefully — that we will not be playing a home game. We don't want to play a home game, all of our games are away games."
