Advantages of leggings (field army):
1, the protection of military pants, in the past, the army could not get a good supply of goods, and the trouser legs were damaged and could not be replaced in time (especially in the field army, one by one, like a beggar gang, what a scandal), so leggings played a role in protecting the main military materials-pants.
2. Leggings act as ropes. Remember the story of an injured Red Army soldier being carried by two other soldiers with leggings in the high school textbook? If you wear combat boots, go there and get the rope, don't use shoelaces.
3. The new leggings have incomparable advantages over combat boots. In an emergency (such as a fire), new leggings can be quickly removed, leaving shoes, instead of taking off the whole boots like soldiers wearing combat boots, but fighting power.
4, protect the ankle, because the leggings can be pulled tighter when fixed, and the protective effect on the ankle is better than that of combat boots.
