While paint ball guns might be of some value in urban-warfare training, there's no way they would be as realistic as the troops' own weapons.

I prefer the paint-ball method..

Reason?

Killed when real ammunition was mixed with blanks..

Soldiers in a training exercise, using standard issue weapons that are capable of firing real ammo, is a recipe for disaster..
How then, does the government explain to the parents that some functionally illiterate soldier "mistook" the real ammo for the "powder ball" training ammo.. and the resultant deaths..

I'm not sure I follow. Are you saying soldiers at ASPs don't know the difference between M855 and, er ... don't know the difference between green tip and scrunchy tip? Or you're mocking some liberal somewhere who believes that?

FWIW, paintball training is better than pointing your weapon and saying, "Bang, bang." All too often US soldiers must do the latter.
