First off, the show seems like they didn't even bother to research basic military procedures. Fighting on duty, securing a perimeter with 9mm pistols, calling out during a memorial service, etc. I could go on but suffice it to say the show's not realistic. I'd be ok with that if the characters were at least interesting or somewhat likeable. They're not. Add to that horrible writing and even worse direction and you end up with a horrible mess that should have been much better.
