Factual error: After Vin Diesel leaps from the truck trailer to attack the mercenaries he elbows a gun that smashes into pieces. For this to happen the mercenary would have had to be holding the gun hard enough that it wouldn't be able to move, allowing the vibrations from the hit to break the gun apart. Even if he were, it would simply break every bone in his hands before falling to the ground, there is no way that the gun would shatter like that in human hands.
Factual error: After the truck crash in the tunnel flour is all over the place and in the air, which is a massive explosion risk. The mercenaries get out of the vehicles and ignore flares, this would cause a massive compressed explosion due to the walls of the tunnel not only immolating everyone in there but likely tearing them apart due to the dispersal of air at an explosive rate.
Factual error: When the main villain throws KT into the wall with his prosthetic arm he only moves his arm. A super strong arm alone would require equal force from both the pushed and the pusher. He would at least have had to brace himself for the push, standing upright like that would have made them both fall over.
