First of all, we all know that red is a very eye-catching color, easy to attract people's attention. In anti-terrorism operations, this red mark on the bulletproof shield will undoubtedly make terrorists and criminals under high pressure instinctively quickly focus on it and attack it. At this time, the counter-terrorist fighters behind the shield can use the moment when they are distracted to shoot to subdue or kill them.
In addition, the attraction of the red mark to the firepower of terrorists and criminals can to a certain extent reduce the possibility of anti-terrorism fighters "hanging up". And the red marked area is often the strongest part of the individual shield, further making the action impeccable.
At the same time, the red mark made of reflective material can play a certain reflective and dizzy effect when terrorists or criminals use flashlights. In a space with insufficient light, the red mark can often make the space behind the shield form a visual black spot.
