Even though the 5th Division did mark some of their jackets the use of TAC marks was way less common then with the 4th Division. It seems in the 4th Division nothing was save from being TAC marked 😮

  1. Would the same be valid for the rest of marine divisions by changing the outlined simbol?

    • I would guess that the basic system must be the same/similar. But not all Divisions seem to have made use of Tac Marks on uniforms and gear.
      The 4th used those a lot, the 5th to some extend and on rare occasions the 1st as well.

  2. Interesting material. I have an early fixed loop USMC helmet – 298 in red stenciled on liner; camo cover with 599 (in red) and 331 (in black) stenciled on the flaps. I have assumed they are UNIS codes? The 331 fits with the 4th Marines, but the 298 and 599 are unknown. Any thoughts?

    • Hi, yes could well be UNIS. Are the numbers within a geometric shape? As for the colours, IIRC white was supposed for infantry, red for artillery and yellow for others. But most of the times it was done in black.

  3. looking for any info on my grand father Draper Overstreet,i believe he was one of the unidentified men at the flag raseing

  4. I have an ID’ed 5th Division helmet and UNIS marked combat shirt which is just as you see in the pictures: rectangle with the numbers 1822, for private, 28th regiment, 2nd Batt., D Company. Got the vet’s full file and these numbers were correct! It was your site here that helped me to ID the grouping. QUESTION: were these battle uniform shirts marked this way only for combat? Or, where they also marked pre or post Iwo JIma? This vet was wounded in the leg and the shrapnel holes go through the left pocket on the shirt and through the paints. Thanks for providing this page!

    • Wow that is great, 5th Division UNIS marked gear is quite rare! I’m glad that my blog was of help.
      Don’t know for sure but my guess would be that uniforms were marked pre/post Iwo too. At least during the preperations for Iwo Jima and the planned invasion of Japan afterwards.

  5. I would like any information about the third Marine Division UNIS tactical marks.

  6. Where were the tactical marks placed on Marine Jeeps during WWII? I’ve seen pictures of them on the front bumper, passenger side. Rear driverside bumperete. Rear of Jeep where Jerry can usually mounted. Passenger side side panel. Doesn’t seem to be standardized. Thank you for any help and guidance.

  7. Any information on the third Marine Division UNIS Code/tactical marks yet?

  8. Thank you for your reply. Please let me know when you find anything.
