In the event of war, military materials of the army are a very important presence. Both building materials and medicinal materials, as well as oil for loading, are the auxiliary materials to ensure the survival of soldiers. There are many kinds of military materials, even sanitary napkins are "one of the important military materials" of the army.

This is not nonsense. A picture of sanitary napkins posted in the army has been circulated on the Internet, which strongly proves the importance of sanitary napkins in the army. This picture was taken at a US military base in the Middle East. Many sanitary napkins were pasted on the military vehicles and sending towers in the picture. People who did not know it would think it was the ultra-thin portable armor newly invented by the United States. However, in fact, soldiers stick sanitary napkins on their vehicles mainly to dry them for easy use next time.

This is mainly because of the large temperature difference between day and night in the Middle East, and the heavy humidity and dew at night. To keep the shoes dry, soldiers often put a sanitary towel on the shoes to absorb the moisture.

Not only that, soldiers will stick sanitary napkins to their helmets and let their heads touch the absorbent side of sanitary napkins to achieve the effect of sweat absorption and prevent them from developing heat rash and eczema in hot summer days.

In addition, sanitary napkins are also used to stop bleeding from wounds. During field operations, if the wound is not treated in time, it is likely to cause wound infection. In case of lack of hemostatic dressing, soldiers can sprinkle hemostatic medicine after cleaning the blood stain of the wound, then apply sanitary napkin on the wound and fix it with bandage.

In fact, sanitary napkins were first invented in the war. During World War I, a large number of new weapons continued to appear, resulting in heavy casualties of soldiers and an extreme shortage of non reusable cotton. Faced with this situation, Kimberley Paper Company of the United States invented a new type of fiber cotton material. This material not only has strong water absorption, but also costs much less than the cotton wool used in the battlefield. After the United States declared war on the Allies, Kimberley Paper Company began to produce medical cotton pad dressings made of cellulucotton and put them into the battlefield in large quantities. French nurses had a strange idea when using this medical cotton pad dressing. This medical cotton pad dressing has strong water absorption. Can it be used for women's "personal hygiene problems"? Later, they used bandages to tightly wrap the medical cotton pad dressings and made the earliest sanitary napkins. Later, nurses in the United States and Britain began to follow the practice of French nurses, using medical cotton pad dressings to replace menstrual bands to solve the monthly female health problems.

In fact, not only sanitary napkins, condoms are also a practical military material. When the US military was fighting on Guadalcanal Island, due to the humid and hot Guadalcanal Island, sediment deposition and numerous flying insects, small insects or sediment often entered the barrel of the gun. When soldiers shoot at the enemy, they often explode the gun barrel because of these foreign matters. At this time, American commander VanderGriff decided to let the soldiers put condoms on the holsters, so that sand and flying insects could not enter the barrel.

Not only that, condoms have other wonderful uses. After soldiers are shot, they can tie a condom to the wound to stop bleeding. When soldiers rest in the field, they can blow up condoms to use as pillows. In the absence of water resources, soldiers can use the temperature difference between day and night to make simple water intakes with condoms. When soldiers swim and shoot on water, they also put condoms on guns to prevent guns from blasting. When soldiers want to store a lot of drinking water, they can also put it in condoms. When crossing the river, soldiers can also inflate condoms to make simple life buoys. Frogman troops in the United States even use condoms to waterproof underwater bombs.

Although sanitary napkins and condoms are only daily necessities for the masses, ordinary daily necessities can also play a significant role under the whims of soldiers.
