The Springfield 03 sniper rifle mentioned earlier, I searched for some information, and it is indeed because I don't know much about firearms and ammunition calibers.

The M1903 rifle was developed by the Springfield Arsenal and produced under license from the Mauser Arsenal in Germany.

The rotary pull-back bolt is modeled after the German 98 series Mauser rifle and can be considered a variant of the Mauser rifle. Outwardly, the overall length of the gun was shorter than that of the Type 98 Mauser rifle, the barrel length was shortened to 610 mm, and the pull handle was bent downward.

Ammunition is fed from a 5-round magazine, and it can be loaded with a 5-round detachable magazine, or it can be loaded directly into the magazine. The M1903 rifle originally fired 0.30-03 ammunition, and in 1906 it was changed to the M1906 rifle cartridge (also known as the 0.30-06 rifle cartridge, Springfield 0.30-06 rifle cartridge) which was an improvement on the Mauser bottomless rim and became the standard rifle ammunition for the next fifty years in the United States Army.

The 0.30-06 rifle cartridge is commonly known as 7.62.

Sorry, but the content has already been uploaded, and if it is significantly modified, it may lead to the situation of resubscribing to the chapter.

In fact, the protagonist with the vision of an eagle does not need a sniper rifle, Garand's range of 800 is enough, positional warfare is not a sniper war, nor is it a sniper war, the role of long-range sniping is not great, and even long-range sniping may lead to the exposure of our army's hidden position, the enemy's offensive mode is artillery fire accompanied by infantry charge, infantry in the process of charging, our army's position is shrouded in artillery fire, when the infantry rushes to a certain distance, the enemy's artillery fire will extend to the rear, freeing up space for infantry charge, if the protagonist long-range sniping, will cause their positions to be observed in advance by the enemy in the rear, and artillery will be called up to concentrate on bombarding the exposed positions.

This is also why we should wait until the enemy is close before fighting, so that our army and the enemy are closer, and the enemy's artillery will not be able to bombard our army.

Writing about the sniper rifle is also in the hope of improving the level of firearms in this world and our country, which will be mentioned in the end.

(Sorry, my question, some fans are more hardcore military enthusiasts, for the knowledge of firearms, I am also checking the information, while writing, there are some insufficient places, this I admit that it is my problem, there is a common sense error, I'm sorry, and thank you for the reminder, thank you.) ）
