I don't know if you have noticed that in many World War II film and television works, American soldiers wear helmets. It's just surprising that
On their helmets there are playing card patterns, red peaches, spades, plum blossoms, squares, which arouses the curiosity of many people, can not help but ask what these playing card patterns represent?
In fact, the 4 playing card motifs on the American helmet represent the 101st Airborne Army, and the 4 suits represent the 501st, 502nd, 506th and 327th Armies. A small white dot can be seen under each suit, if you see a white dot at 12 o'clock, it is the representative of the regimental headquarters, if you see a white dot at the 3 o'clock position, it represents the first battalion, and the white dot at the 6 o'clock position represents the second battalion, and the white dot at the 9 o'clock position represents the third battalion.
In fact, the reason for these colors and white dots is that the ultimate purpose is to allow paratroopers to find their own troops in the shortest possible time after landing on the ground in the air, so as to avoid chaotic scenes. On the battlefield, as long as you see the squares, you know that it is the 501st Airborne Regiment, the red peach indicates that it is the soldier of the 502nd Airborne Infantry, the white peach represents the soldier of the 506th Airborne Regiment, and the Plum Blossom is the 327 gliding airborne. I have to say that the idea of the US military is quite novel, but the effect is very good, and it greatly reduces the chaotic scenes that may occur.
However, such a suit is also easy to cause ambiguity, for example, the three battalions of the 506 airborne infantry regiment use a short crossbar on the left side of the white peach, in fact, the logo of the first battalion is used by the three battalions, that is, the right side plus a short bar, the next battalion is blindfolded, and no one knows what is going on. Many years later, the people of the first battalion found out that all three battalions had made mistakes at the beginning, but in order to avoid trouble, everyone would be wrong. But in general, it still plays its due role, that is, to allow soldiers to quickly find their own team.
In addition to the pattern of playing cards printed on the steel helmet, the belt that fixes the helmet when the American soldier is marching or fighting is always in a state of "unraveling". To be honest, let the helmet hang naturally, there is indeed a feeling of handsomeness, is it just because the American soldiers are debauched and love freedom? Even when some soldiers are running, even if they cover their steel helmets with their hands to prevent falling, they will not send the strap to their chins. Whether the U.S. military discipline in World War II is relatively loose in this regard, or like they like to hang grenades on their chests, in fact, it is not.
Steel helmets are individual protective equipment to protect the head from injury, basically steel helmets are composed of three parts: shell, lining, and suspension system. The shell can resist the direct blow of shrapnel, while the lining can slightly reduce some impact, and the suspension system is the elastic band on the helmet, which plays a role in fixing the helmet and adjusting the wearing comfort.
During World War II, most of the American soldiers were equipped with M1 steel helmets, and the reason why few people tightened the jaw belt was the structure of these three parts. As everyone knows, the M1 steel helmet can only be regarded as having two parts, shell and lining, because its suspension system does not exist independently, but is directly welded to the shell, which leads to the fact that in the battlefield full of artillery fire, the M1 steel helmet may also die when protecting the soldier's head.
During World War II, many legendary soldiers emerged, and Audi Murphy was one of them. His memoir, "The Return of a Hundred Battles and Glory", has such a record, saying that when he first joined the army, he was told by the sergeant not to tie the straps on his helmet tightly. After all, the strap and the helmet have been welded together, and the shock wave generated by the bomb explosion is likely to fly the helmet, needless to say that the head will also fly away, which can be said to be the direct reason why many soldiers are reluctant to tie the jaw belt.
There is also a situation in which American soldiers do not tie their jaws when they engage the enemy in hand-to-hand combat. They feared that once the enemy grabbed the strap of the helmet from behind and pulled it back, he would lose his life when his body lost his balance. It seems that the same as the grenade hanging on the chest, wearing a steel helmet but not wearing a jaw belt, is not the American soldiers in order to play the arrogance of the cool, and the military discipline has nothing to do with military discipline, are soldiers in the rain of bullets and bullets, in order to survive to sum up the survival experience.
