The bazooka damage varies wildly in the movie.
Jade and Rowdy are in a jeep when the tire is shot out with a shotgun. Somehow Jade is also injured, even though it's clear that the villain only shot at the tire. Additionally, after Jade and Rowdy dispatch said villain and drive off, the tire that was shot out is not flat.
The skater getting tossed into the air, with his inflatable doll, has blood on his shirt. In subsequent shots, the shirt is immaculate.
The position of how the frisbee is being held, by one of the victims when he gets inflicted by a razor bladed one.
When the skater and the blow up-doll are shot out of the air, the wires suspending them are visible and the skater is replaced by a dummy.
The skateboarder assassin somehow shoots Jade and the Jeep's tire out with an H. Koon .410 "Snake Charmer" shotgun in one pass, while holding a blow-up doll. It is a single-shot weapon that has to be manually reloaded after every shot.
When Rowdy drives his motorcycle out of the back of the van, it's clear that the motorcycle is already on the ground - and is not coming out of the van - as you can clearly see it resting on the earth.
When one of the bad guys catches the razor bladed frisbee, the fingers on his catching hand slice off. But in the next shot, when he's harmed the frisbee and holding it with the same hand, no harm is done.
When the helicopter is shot down with the rocket gun, a wire is visible holding it up and the blades are no longer spinning.
When the helicopter is shot down and blows up in mid-air, you can clearly see the rod it is hanging from at the top of the screen.
When the team set off along the beach in a 4WD to attack Romero's compound, there's a crew member, clearly visible in a bright red shirt, standing next to the vehicle before it starts moving.
