Continuity mistake: When Bennet and Matrix are fighting at the end. Bennet has his hand over Matrix's face. During instant camera cuts, the position of his hand alters on Matrix's face and neck. (01:18:55)
Continuity mistake: When Arnold throws the pipe at Bennett the end of it is round and clean; in the following shot it is irregular shaped and edgy. (01:20:00)
Continuity mistake: At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide shot, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the coast. Even if the boat was off camera during the landing scene, a few minutes was surely not enough to get that far, and that close to the shore. (01:20:30)
Continuity mistake: At the end when Alyssa Milano is standing next to Arnold, in the wide shot you can see it's him, but in the close-up of Alyssa the person standing next to her has blond hair on his chest while Arnold is well "shaved clean". (01:21:30)
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: 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)
Continuity mistake: In the fight scene where Matrix and Bennett are trying to force each other against the furnace, watch Bennett's hands as he struggles with Matix. In one shot Bennett has his hand pressing against Matrix's face, in the reverse shot he is holding Matix by the back of his head/hair. His hands switch back and forth several times. (01:23:00)
Continuity mistake: During the fight at the end of the movie between Matrix and Bennett when Bennett calls Matrix a "dead man" and he responds with "Bullshit" you see him come off the wall with his left hand. He is throwing a left hook, but in the very next shot when the punch comes in contact with Bennett his fist is going from right to left in a backfist motion, rather than a left to right hook. (01:23:45)
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: At the end, where Matrix kills Bennett by throwing a pipe through him (OK sure, but let's just pretend). The pipe goes through Bennett, and into a steam pipe behind him. Then steam pours out of the Pipe that Matrix threw. Now what happened to all of the flesh, bone, skin, and blood that was inside of the pipe? (01:24:00)
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)
Continuity mistake: When the movie ends and Matrix is about to get in the hydroplane, the faded paint on his nose becomes much darker. (01:26:10)
Continuity mistake: During the car chase there is a silver Renault 5 which is behind the Porsche and in front of Arnie, two or three times Arnie overtakes it, yet in the following shot he is right behind it again. (01:38:43)
Continuity mistake: In the final fight scene Bennett opens a furnace door into John's face, knocking him to the ground. When he opened the door it was two half-doors that opened together, yet in the next shot when he rips the door off to throw at John, only the bottom half is still there.
Continuity mistake: Right when the fight between Matrix and Bennett begins, the Uzi submachine gun vanishes from Bennett's right shoulder (it was on a strap). Then suddenly at the end of the fight (after the fell down over the railing and to the next level down, the Uzi reappears when Bennett picks it up and attempts to shoot Matrix. Bennett lost it on the upper level nowhere near the railing, and it somehow appeared on the lower level away from the railing.
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.
