Stupidity: While running "silently", the SONAR keeps beeping. Active SONAR is akin to yelling "Polo" in a pool.
Stupidity: Milton, straddling Edie's body on the floor, is about to pull the plastic sheeting over her head. Edie's eyes suddenly open, and she starts screaming. Instead of quickly pulling the plastic sheeting over her head and suffocating her, Milton half-heartedly struggles to control Edie's hands, which she somehow manages to raise from alongside her body and around his to be in front of her neck.

Stupidity: The team raids the house and locates 5 people inside deemed to be Russian operatives. They are subdued and placed on their knees, while some of the team works on gathering intel from the home. The subjects should have been handcuffed/zip-tied. Since they were not they were able to grab stashed weapons and cause a gun fight which led to one of the entry team's members being killed and all the Russian operatives killed. It's common knowledge to restrain people. Cops and military always restrain. (00:04:00 - 00:12:00)
Stupidity: A-X-L was supposed to be a highly sophisticated and intelligent robotic dog yet it let Sam torch it (without even trying to back away from the flames) and let drones attack it on two separate occasions, each resulting in A-X-L being incapacitated. A-X-L also fell and rolled down a hill, smashing itself. An advanced machine should be able to stay upright! It also seems odd and out-dated that a robot would run on gasoline.
Stupidity: Outside the bank, Mike and the first merc are having a shoot out across the parking lot. There is lots of room between them and around them. Yet a random construction worker, with a clear view of this shoot out happening, suddenly decides to take off running into the line of fire between the cops and the robbers and gets shot in the leg. Their was no reason for him to suddenly decide to run between them shooting at each other into the line of fire. (00:44:35)
