A sweet 600th Video. Clyde tested both alert and attack. I had no idea attack would be tested, but wanted to do a distant video of this 3T22 where the dampers close upon activation. Alert still sounds the same but this gives off insane echos when it winds down and during attack. You may hear 2 T-128's in the distance as well, but man Im sure glad I didnt go to LaPorte county (wink wink)
