Yellow MK2

BOCN Supporter
Hello all. Can ayone tell me when the MK2s stopped being yellow? I only ask as I was looking through mymates photos on facebook and he ws an extra in some film as an American soldier fighting the Japs in 1945. He has a yellow MK2 on his belt, but I thought they had used the green body, yellow stripe by this time.

I'll have to double check but if my memory serves me correctly, the Ordnance Committee approved the change in 1942 so it would have been rolled out soon after that.

That doesn't mean that all yellow ones weren't found in service after that, it just means that they hadn't been shipped back to the Depot Level for repainting.

Edit Update:
Ok in my digging I'm seeing that the original request was a letter on April 8, 1942 for painting bombs with infra-red reflecting olive drab paint. The issue was further discussed in the OCM meeting on 12-10-42 in which the Sub-Committee recommended the following:

a. That all H.E. bombs and separate loaded H.E. ammunition be painted with lusterless olive drab paints containing available infrared reflecting pigments. Formulas for suitable infra-red reflecting paints of adequate stability and which do not contain critical materials, are available and will be incorporated in the specifications.

b. That other ammunition, fixed ant semi-fixed rounds, rockets, grenades, mines, etc,, except Small Arms, remain as they are at present with the following exceptions:


I. That all colors used on ammunition be lusterless instead of the present semi-gloss, to dull finish.
II. That the yellow color now in use as a base color on H.E. ammunition be changed to a lusterless olive drab with No, 4 yellow stencil to designate H.E. filler.
III. That all wooden ammunition boxes used in the transportation of ammunition to the using services be stained a light brown color to decrease their visibility.
IV. That all metal parts on the exposed portion of the ammunition boxes and containers be painted with a light brown lusterless enamel.


c. That a lusterless color card be prepared to show lusterless
color including infra-red reflecting colors, for use on ammunition, similar to the present color standards issued in connection with specification No. 3-1; General Specification for Paint, and Related Materials.


d. That current stocks of artillery ammunition packed in fiber
or other containers in which the ammunition is issued to troops need not be repainted. Current Stocks of separate loaded ammunition will be repainted if and when practicable. Current stocks of bombs, which are now painted with lusterless olive drab without infra-red pigments need not be repainted. Current stocks of rifle grenades, hand grenades and rockets in depots will be repainted to conform with these recommendations.
Stocks of rifle grenades, hand grenades and rockets in hand of troops will be repainted if and when practicable.

So there, the official date is 12-10-42 as the report was approved by the Ordnance Committee and approval of higher authority was not required.

Just a guess, but the color yellow had previously denoted the contents of ordnance as having an HE filler.

I've heard two possibilities. One was the HE content anf the other to guard against loss. Seems like a combo of the two to me.
I'm surely no expert as I just purchased my first one of I hope many more to come.

Ya see, I have this problem...
 
I find it extremely hard to comprehend the U.S. would enter the war with bright yellow grenades. May as well hang a bullseye on you! Dano

I never understood this either. I get the whole yellow denotes HE thing, and the military being the military, stuck with regulations. But I wouldn't be too excited about the idea of going into combat with yellow anything. It's crazy to think that many people did just that! Hats off to them!
 
Anyone know why they painted them yellow in the first place ?

Ask and ye shall receive:

MINUTES OF THE ORDNANCE COMMITTEE MEETING
HELD THURSDAY MAY 6, 1926
AT 10:30 A.M.

ITEM 5404

PAINTING OF FRAGMENTATION HAND GRENADES:
Mr. Adelman read the following report on Grenades:

1. References:
0.0. 471.611/636
0.0 471.611/647

2. In Report No.7 of the Marking Board, Ammunition etc., dated February 21, 1919, it was specified that a fragmentation grenade shall be painted gray when loaded for combat use. Picatinny Arsenal is now preparing a specification for loading of fragmentation hand grenades, Mark II, with TNT. These grenades, when manufactured, are painted Battleship Gray, according to Specifications EW 514-5, paragraph II 5.

3. At the present time, the chemical ammunition is painted gray and in addition to other markings, there are green bands to denote persistency. In keeping with the recommendation of the Marking Board, high explosive ammunition is designated by the application of a specific color, yellow.

4. The sub-committee recommends that high explosive grenades be painted yellow, the color now prescribed for painting H.E. projectiles.

Action required by: Manufacturing Service.

A motion was made, seconded and carried that the report of the Sub-Committee be approved.

As stated above, yellow H.E. grenades continued in the supply chain. They were not all returned to depots for repaint to green / olive drab. Many were done in the field. Here is a photo I cliped off line... maybe from this site, of a field re-paint job in progress, August, 1943.

Great Pic, thanks for posting. It's a Jarhead BTW. The Marines always got the old stock gear and equip.

Here's pics of a USMC booklet dated 1943 that mentions yellow grenades should be painted different, and also some other interesting ord related info.

Regards, Steve
