Camouflage: OCP (often mistaken for MC Camouflage, cottage manufacturers are often mistaken for CP Camouflage)
Installation: US forces in Afghanistan
The original OCP camouflage used by the U.S. military looks very fuzzy in color, and the overall tone is like old clothes. The bright colors in the drama "Special" are wrong, and it can be seen at a glance that it is a domestic imitation. Taobao has it, which is not expensive. You can get it by searching for "tight combat clothes".
Similar to this OCP camouflage, there is MTP camouflage in active service in SAS, England, but the difference between them is very significant in color block and tone, and the latter draws lessons from the former in research and development. The picture below shows the difference between the two (the American general on the left is OCP and the one on the right is MTP).
P.S.: Don't copy my answers just for a book that is read more than 13. My answer to other people's questions was wrong, because I didn't look carefully at it at that time.
