Continuity mistake: When Matrix is in the gun shop, you see him take the missile launcher off the wall, but then in another scene, it is back on the wall again. Also, watch how easily Cindy runs with the missile launcher to the shopping cart. I guess those things don't have any weight to them. (00:55:17)
Continuity mistake: The style of Cindy's car changes when Matrix and Cindy are tailing Sully. Note the front grille with the center emblem that suddenly appears, the style of the headlight chambers that surround the headlight casings, as well as the two bumper guards that disappear and reappear. Obviously different vehicles. (00:30:30)
Visible crew/equipment: In a scene towards the end, you can see the two bad guys flip into the air, and see the air ramps they fly off. (01:13:24)
Continuity mistake: When Matrix is fighting with Bennet at the end of the film with the knifes, when Matrix slashes Bennet's wrist if you look at the knife it has no blood on it. (01:22:00)
Continuity mistake: In the mall, before the girl enters the bar, a guy in a blue and white shirt is half a metre away from passing next to her. Camera shot on Arnold, then back to the girl, and now the walker, plus the passers by around, have stepped backwards several metres and repeat their movements again. (00:31:55)
Factual error: Arnie drops from a plane travelling well over 100mph, falls about 100 feet, and just because he lands in a marsh, doesn't mean he'd be uninjured... (00:24:39)
Revealing mistake: In the mansion, Matrix jumps to shelter in some flowers and the mat he lands on is noticeable because he bounces and parts of it become visible. (01:12:10)
Continuity mistake: During the last fight, when Bennett and Matrix fall over on the platform, the gun on the floor to the right side of the screen moves around between shots, allowing for Bennett to easily pick it up. (01:18:20)
Continuity mistake: When Bennett is beating the crap out of Matrix by the furnace, the close shots show big bleeding wounds, which disappear or diminish drastically in the wide shot. (01:22:25)
Factual error: When Cindy first gets into the seaplane, she asks 'where are the LCD readouts? - I learned in a Cessna' as well as saying 'this plane is older than I am.' Any Cessna she learned to fly in would almost certainly be older than her, but even worse, Cessnas used for initial flight training (150s, 152s or 172s) certainly do not have LCD displays. (01:00:20)
Continuity mistake: During the long shoot-out at the compound, Arnold shoots down a whole army of bad guys. When he reaches the fountain, he shoots at about 3 or 4 people from a bird's eye view. If you watch closely, you can see one of the guards dive on the ground and play dead before Arnold's stream of bullets reaches him. Given what was happening at the time, that may have not been a bad idea. (01:12:45)
Continuity mistake: After Matrix kills Sully he tips the yellow Porsche back on its wheels and we see the hood ornament is gone. As he and Cindy drive away it's magically reappeared. Then as they go through the city it's gone again. (00:41:50)
Continuity mistake: When Sully flees the mall in his Porsche he runs into Matrix, knocking him up and over the car but also knocks off his wing mirror in the process. In the driving scenes that follow the mirror is back on the car. (00:37:40)
Continuity mistake: When Bennett holds his knife against Matrix's face the knife keeps swapping positions and also the blade appears up or down depending on the shot; despite Bennett being unable to move his arm. (01:18:10)
Revealing mistake: There is a scene in the mall fight between Matrix, and the security guards when he knocks one of them over a railing you can see the cord that's attached to the security guard's right ankle as he falls. (00:34:45)
Continuity mistake: The position of the pipe stuck in Bennett's chest moves down and to the left in the second shot. (01:24:00)
Continuity mistake: Sully is a very short man and Matrix is a very tall big man. Yet after Matrix kills Sully he gets in his car and drives away without having to adjust the seat at all. (00:41:45)
Continuity mistake: When Matrix is trying to ram Sully off the road, the amount of damage to both cars is constantly varying. (00:38:10)
Continuity mistake: The amount of juice in the glass when Matrix has breakfast with his daughter suddenly changes from a third to over a half of the glass. (00:07:40)
Continuity mistake: At the end of the film, when the Army are arriving on the island, the amphibian plane is beached, with the nose facing the beach and the camera. In the next shot, when we see the same plane again, it has been moved out about 50ft, and turned round. (01:26:00)
Answer: They didn't know where Matrix lived. They were killing Matrix's old unit because they knew if they did General Kirby would make physical contact with Matrix to warn him. They simply followed Kirby to Matrix's home.
