I dont have any probles with these drills. I think our military should be as prepared as possible before they go into combat. Not having them fully prepared would be an extreme disservice to our men and women in uniform.
Is it hilarious that I feel like modern warfare is the exact reason why the military is starting to do drills like this. To be honest with you the first time I ever seen anything similar to Americans actually fighting on their own turf is when I watched modern warfare the videogame. I don't think Americans are even trained to fight on their own turf all their training involves them fighting overseas.
A lot of people think these things are bad, but I don't know about that. Sure the drills might be useless, but riots happen all the time. It is better to be prepared then not. If you want to talk about the militarization of the police, that is a different story.
