What symbols are there in sniper movies?

We are very strict in the army, and snipers are also very strict arms. For snipers, not only accurate shooting is needed, but also strict requirements for field viability are needed. It can be said that the sniper is a magical existence, omnipotent. Of course, being a sniper is also an honor.

Nowadays, the role of film and television is also very magical for snipers, as if they can climb over the eaves and do anything, and the shooting accuracy is very high, even with one shot, so everyone worships snipers very much.

But I don't know if you noticed one thing when watching TV, that is, the sniper's bullet will have a mark similar to the word "ten", so what does this mark mean? It really makes people curious. Some netizens speculate that this cross is to mark their bullets, but isn't this equivalent to exposing their sniper's identity?

In fact, this cross is not carved for marking, but to increase the resistance and friction of the bullet in the air, so that the lethality of the bullet to the target increases, so the sniper will have a mark similar to the word "ten" on his bullet, which can not only increase the resistance, but also hurt the target.
