Yesterday and last night my soldiers and I were training on how to enter and clear a building. In the picture, I'm #2 in line to enter a shoot house. We were training on "city fighting" with night vision goggles and blank ammo. Three of my NCOs are "stacked up" with me: SFC Nash and SGTs Cos and Basco.
I hope that we never have to use this training for real.
