EOD guys never travel alone or enter an area before it's cleared out. This would invalidate about half the scenes in the movie just by itself. At the end, they would not be chasing enemy combatants at night through crowded streets. They would not then split up, that is suicide. The main character would either (1) not be alive after acting like that in Afghanistan or (2) have been relieved of duty long ago. Throwing a smoke bomb? Are you serious?
We can also break down the sniper scene, which was by far the worst:
1. They're driving through the desert by themselves? And encounter soldiers who had driven through the desert by themselves?
2. The soldiers hadn't notified anyone that they're broken down outside the wire?
3. They didn't reveal themselves as soldiers until the US soldiers had exited the vehicle and put a gun to their heads? Are these people suicidal?
4. The US soldiers didn't notify anyone that they had encountered a broken down truck?
5. They get sniped at X distance from a building that nobody apparently noticed up until then?
6. They respond to the sniper by going INTO the sniper's line of sight and BREAKING OUT A 50 CAL?
7. Why didn't they call in an airstrike or at the very least radio in that they were under fire?
8. Nobody reacts at all when compatriots are shot and killed. Reloading the 50 cal, that nobody can apparently aim with, seems to be the higher priority. Are they robots or human?
9. He can't hit the bad guys that are standing still but hits a guy running at full speed?
10. They're being flanked by unknown number of bad guys, and they don't even flinch and tell one soldier to "deal with it."
It was a fucking ridiculous movie not at all based in reality.
