Like future historians will say that it was used to brainwash kids into glorifying war and joining the army. Kinda like how in Metal Gear Solid 2 [Metal Gear Solid 2 Spoilers] Snake says that Raiden's VR training was used to take the reality out of war. He never felt pain, and never felt bad for killing someone. He thought that he would be prepared for real gunfights. Now that I think about it, the MGS2 plot fits kinda good with CoD replacing VR training. >_> --- HELLO!!!
Yeah except for the whole slogging through miles of mud or a desert and being shot at.
That usually will snap you out of the idea that it's just like a video game.
see also: drone strikes
Drone strikes will only get your so far. Dudes on the ground ready to annihilate people is how you win wars. Kinda like how people from the 1960s to the 1990s through you could completely fight a war from the air and just bomb stuff. Drones are only a tool/force multiplier, not a replacement.
Which now I think about it oddly enough, is the point of BO2's campaign. --- Big Money. Big Women. Big Fun. I don't have a cocaine habit, I just like the way it smells.
