helmet cover 1a kleinIwo Jima, March 1945

Unique to the combat marine of WW2 is the use of the camouflaged helmet cover.

Many contemporary photos taken in the Pacific Theatre of Operations (PTO) show that 90% of the helmets are covered with this piece of combat gear. The first offensive action fought against the Japanese was on Guadalcanal in a lush jungle environment. On the ‘Canal the marines wore the newly introduced M1 helmet. This helmet was worn stark naked, and produced a shiny glare when wet.

Already before the fighting on the ‘Canal started, the US Army and Marine Corps were searching for a special camouflaged jungle combat uniform. The first garment developed and produced was a one-piece coverall, which was ill suited for jungle environment. Often ridden with disease, like dysentery, the call of nature was frequently, and, immediately! One would have to shed equipment and strip the coverall before relieving himself. Some men just cut a hole in the seat of the suit. Proven unsatisfactory it was soon replaced with a two piece camouflaged suit by the Marine Corps. (The Army did also introduced a two piece camouflage uniform, but never got past a combat test at the European front in Normandy.)

The two piece camouflaged uniform was based on the USMC’s P41 Utilities, but fully reversible with a dominant green color scheme for jungle and a brown scheme for beach environments. To top this combat uniform a reversible helmet cover was designed. Made from the same camouflage material as the fatigues, this cover was made to fit the M1 helmet 


Foliage slits (buttonholes)

It’s design dates from September 17, 1942. There is only but one design for the helmet cover adopted. This design called for two halves of Camouflaged Herringbone Twill (HBT) sewn together, each half with two rows of 4 horizontal “buttonholes” on the upper half and one vertical hole in each flap. Although not intended to button anything to the cover, these one inch long stitched holes are called “buttonholes” in the original documents.

1st version produced

3rd type

Button holes in crown and flaps.

The first batch delivered and issued is with those buttonholes. It's sometimes hard to tell from pictures, but the early campaigns show mostly, if not all, covers have slits. It has long being thought that the early produced covers didn't have slits and that only later productions covers had these added. The document shown above prove otherwise. The base solor on the "green jungle" side is of a light pea-green khaki-ish color.

Collectors sometimes refer to these as the “third”type.

2nd version produced

No button holes.

It was found that, when in motion, using foliage for camouflage made the user more conspicuous. It is most likely that after further field test the production of helmet covers with foliage slits was discontinued some where in 1943. In later operations (1944 and 1945) a mixed use of covers with and without slits can be observed. The base color of the "jungle" side is of a darker pea-green color, consistent with later produced camouflage HBT.

These are referred to as the "first" type by collectors, although it is really the second version produced.

3rd version produced

Only button holes in the crown. (click photo for close up of the nomenclature stamp.)

These WW2 productions were used up after the war during the Korean War. 

When the existing stocks were depleted, new covers were ordered. All these covers are 1953 dated. This new production had the foliage slits in the crown again, but were without the vertical buttonholes in the flaps.

Sometimes these covers are referred to as the “second” type. (But this was the third and final version to be produced.)


Another myth surrounding the helmet cover is the use of an EGA (Eagle, Globe and Anchor) stamp on the front of these covers during WW2. None were stamped that way and the covers found nowadays are indeed of WW2, or 1953, manufacture, but were stamped in the postwar years (late 50's). Having one in your collection doesn’t prove that the dark spot on a blurry photo is indeed a EGA stamp. No contemporary photo supports any claim as proof of this practice.


Often this photo is used as "prove" that Marines stamped their covers with EGA's. Although it is a wild bunch, the Marine on the left holding the flag has NOT stenciled an EGA on his helmet, It's just a spot.

A 1956 directive called for a diamond shaped patch of the same material as the helmet cover stenciled with the contemporary EGA. One for each side (jungle/beach) of the cover. These are rare to find and probably done on a small scale. It is interesting that this practice was done with the old frog skin HBT covers as well as the new cotton Mitchell pattern covers.


The following is pure speculation! Producing and sewing on the new diamond shaped patch would require that all the covers in stock (anywhere around the globe) would have been called back to alter them to new standards. Or, to do it locally, if facilities were available. Perhaps it was considered easier and cheaper just to stencil them with the EGA logo. This EGA stamp is solid like the ones stamped on the WW2 utilities, but without the cable and scroll. When this was done is not clear.

Fitting the cover was easy, just pull it over the steel helmet and fold the flaps over the edge inwards. Replace the liner, thereby securing the cover. Make sure that the helmet’s chinstraps stay clear between two cover flaps. Since the cover is a little larger than the circumference of the helmet’s edge, it can’t be pulled tight around the chinstraps. To elevate this marines usually cut a hole for the straps to pass through.

It is interesting to notice that during the Guam campaign most marines of the 3rd Marine Division went bare helmeted. Although this division used the helmet cover in the previous campaign, photos show that on Guam the majority of the leathernecks went without the cover. The reason for this could be that after the Bougainville campaign the division was issued new clothing and was ordered to turn in their worn camouflaged utilities. Most marines probably turned in the complete set, including the cover, while a few kept them. The new clothing, then, failed to come with a fresh helmet cover. Hence, a lot of naked helmets! (This all is pure speculation from my part again.)

It is interesting to notice that the WW2 marine didn’t buckled the chinstraps around the back of the helmet. Since this was “army”style it was severely frowned upon. Most marines wore them buckled under the chin, or let them hang unfastened. Only during the Okinawa campaign some Marines from the First Marine Division buckled the straps around the back of the helmet.


These men are from the 1st Marine Division on Okinawa. Note that they both have their helmet straps buckled "army style".

Because of the sun beating down on them all day, some marines let the flaps at the back hang loose from the helmet, instead of tucking them in between the pot and the liner. This practice is referred to as “French Legionnaire”style or "Arab" style:
"To protect themselves against sunstroke, the men pulled out the cloth camouflage cover on their helmets, let it hang over the back of their necks, so that they looked like Arabs." (The Old Breed, official history of the 1st Marine Division in WWII)

One other style of helmet cover was issued during WW2. Often referred to as the “sniper cover”, it sports a camouflaged face veil. Made of thin cotton this was a non reversible cover printed with the green camouflage scheme. Stitched around the the cover was a green fabric tape for attaching foliage. To the edge of the cover was sewn a green camouflaged printed gauze like material, hemmed with tie-down tapes. The sole purpose for this veil was to ward off insects. The tapes were to be secured under the armpits. This practice was not popular and the nets were tucked between the steel pot and liner. Most of these covers were issued to rear echelon troops.
