will not. First of all, the visible laser pointer can easily determine the shooter's shooting point. Even with infrared lasers, even basic NV equipment can see the beam. Second, the laser light travels in a straight line. No bullets. As soon as the bullet leaves the barrel, it begins to be affected by gravity. When the shooter shoots, the barrel is pointed higher than the target, and the bullet falls on the target. It has also been adjusted for wind and other environmental factors. Unless the sniper zeros the laser and weapon in the proper range, and there is no wind declination. Otherwise, the laser pointer will not be aimed at the target.
Third, in a longer range. The sniper may not be able to distinguish the visible laser pointer. Although there may be TV and movies that will convince you, it is difficult to draw details at long distances even in the high power range, so it is unlikely that the sniper will see this point anyway. The target size is 600 yards (548m), and it is a humanoid target with 25 times magnification, which is the medium range of an ordinary sniper. This is the same as the maximum magnification of the scope used on the L115A3 sniper rifle. Can you draw a 3mm wide laser pointer red dot within this range?
