Brand? PROPPER in Tennessee, and then it's gone ~

ECWCS GEN I is suitable for all military species.

ECWCS GEN II is mainly used by the Marine Corps, but it is rarely used by the army. I don't know if the soldiers bought it privately.

There is little specific information about ECWCS GEN III. I've only seen ACU colors. It is said that there are experimental and official versions. I don't know, the version is the second generation.

APECS, the name of the Marine Corps, is a substitute for GEN II, and now the Air Force is also using this style ~
