3RD DIVISION NUMBERING

There has been no official USMC publication that I have been able to find for the 3rd Marine Division UNIS markings. It is very unusual to find any markings on clothing attire. The majority of markings seen have been on 782 gear.

The 3rd Marine Division marking is a flattened broken line triangle with three numbers within the triangle.

It is important to clarify that the 1st Marine Division used a vertical broken line triangle.

I list here all the known examples I have seen to date. Some were named, so the unit could be ascertained. This is the only way of discerning the numbers.

Therefore this is an ongoing project to build a data base of numbers.

3RD = INFANTRY

9TH = INFANTRY

12TH = ARTILLERY

19TH = ENGINEERS

21ST = INFANTRY
