Arizona -(Ammoland.com)- I received this photograph from a source who was looking to identify what type of “gun” it was.  I believe it is a field improvisation of four .30 caliber M1919A4 machine guns in a linear quad mount. It is designed for use on ground targets.

You can see that the quad .30 calibers command a significant amount of the terrain in front of them.  The .30 caliber has a maximum effective range of 1,500 yards, a bit short of a mile.  As a quad mount, that range would be increased  a bit.

There is no way to elevate the muzzles far enough for effective anti-aircraft fire. The base of the Korean mount is from the M63 Anti-Aircraft mount for the M2 Browning .50 caliber machine gun. (H/T to archy on freerepublic).

The other quad mounts that I have seen were designed for anti-aircraft fire.

The Soviet quad mount of 1910 Maxim machine guns is set up for anti-aircraft fire. The image is from a display in a Russian (Soviet) Museum.

 

Korean War Field Innovation Quad .30 Caliber Anti-Personnel

The Korean war was noted for its mass wave attacks by Chinese soldiers against American troops.  The anti-personnel quad .30 caliber was likely a response to those attacks.

Quad machine guns have often been used against ground targets. The quad .50 caliber M2 was often used in that way. But the mount was designed as an anti-aircraft mount. The From koreanwaronline.com:

Highly effective as an anti-aircraft weapon against strafing attacks in World War II, its primary deployment in Korea was as a devestating antipersonnel weapon.

The Quad-50 was still used during the Vietnam War, in semi-fixed locations to protect the perimeter of fire bases, and very effectively on motor convoy support.

The .50 caliber machine gun is primarily an anti-vehicular weapon. Its weight, and the weight of its ammunition, make it unsuitable for mobile infantry use. However, in semi-fixed positions such as the MLR in Korea, or mounted on vehicles in file, as in the withdrawal from Chosin, the weapon is magnificent. Its great range and striking power make it deadly in enfilade against troops staging for assault. Again, these capabilities make it ideal for quick reaction against machine gun and mortar positions on heights overlooking road communications.

Vickers had a 12mm quad mount for shipboard anti-aircraft defense between World War I and World War II. The round was a bit less powerful than the .50 caliber Browning M2.  It does not appear to have been used in an anti-personnel role.

American soldiers have been known for field innovations in a number of wars. Supposedly, a German general said of Americans in WWII: “You cannot depend on the Americans.  They do not even follow their own rules.”   I have not been able to verify that quote.   It is likely that the quad .30 caliber was a “one of”.  Sometimes field innovations work so well that the military chain of command takes notice and incorporates them into standard equipment.

If alert readers have any information about the Korean War quad .30 caliber mount, its deployment, development, or use, We would like to hear from you.

My father a forward observer in the army during the Korean War mentioned to me a quad .50 or 30 he saw at one place on the front . Note he thought it was a 50. He saw action in many big and small battles including the Chopin reservoir, battle of the white horse and many others interesting to see one in this configuration. The quad mount I pictured was vehicle mounted and had 2 guns one over the other on two sides.

the attributes to that comment range from German to Soviet. Nonetheless, it would seem that it is believed and that the anecdotes that affirm it reveal the truth behind the statement.

Re “you cannot depend on Americans to follow their own rules”, thank heavens for that.

@Alan, There was, also, a German general that said, The Americans are so good at war because war is chaos, and the Americans practice chaos every day. He should have taken his own comment more seriously.

Dean, Great article on the quad .30. One of my friends used dual Ma Deuces during Viet Nam on a quick reaction vehicle. There is such a truck at the Transportation Museum, Ft Eustis called the “Eve of Destruction” . I think that the “Red Ball Express” also used such vehicles during WWII in case they came under attack while on supply runs. The statement: “You cannot depend on the Americans.  They do not even follow their own rules.” I believe it was attributed to Field Marshal Keitel during the Battle of the Bulge. I will keep looking and let… Read more »
