I'm glad that you find that hilarious! Been deployed as 11B in Iraq and I can tell you from personal experience that one country can go from good to crap in hours.
Also I'm a former APD officer and had active shooter training. But I don't expect a call of duty video gamer to understand this...
This is my active shooter kit, and if SHTF also
Banshee plate carrier w.6 pmags and tripe decker taco pistol pouches. I have sapi plates,
Also I use battle belt, is an ATS tactical with Kydex holster, IFAK, dump pouch and two frag pouches where I put my compass and Head lamp
