Call Signs

– 9th Infantry Division Call Signs

9th Infantry Division Radioman

The 9th Infantry Division radioman had to know all the call signs.

In wartime, communications between Divisions, Battalions and Companies had to be done by using so called “Call Signs”. This was a “code” word for each group to protect any form of information that might fall into the hands of the enemy. These call signs can often be found in radio conversations and reports.

During World War 2, the first letter of a Division would usually be the first letter of the call sign name. The code name assigned by the US Army to the 9th Infantry Division was “Notorious“. All components of the Ninth Division were given code names that started with the letter “N”. After doing some research, I was able to find several of the call signs that were used by the 9th Infantry Division. In some of the radio reports we can see how these call signs are being used. Some of them are actually pretty funny to read.


The call signs:

Battalion codes:

The Battalions were given the colors of the 9th Infantry Division shoulder patch from the top to bottom:

Battalion Call Signs

Battalion Call Signs

Battalions:
1st Battalion =Red
2nd Battalion = White
3rd Battalion = Blue

Company Names:
The battalions were made up of companies:

1st Battalion:
A = Able
B = Baker
C = Charlie
D = Dog

2nd Battalion:
E = Easy
F = Fox
G = George
H = How

3rd Battalion:
I = Item
K = King
L = Love
M = Mike

If we take a look at this code name example:

“Nutmeg Red Able One Leader”

It can be decoded as:

Nutmeg = 60th Infantry Regiment
Red = 1st Battalion
Able = Company A
One = 1st Platoon
Leader = Leader

This translates to being the 1st Platoon Leader of Company A, part of 1st Battalion, 60th Infantry Regiment.

US Army Staff Designations:

Then we have these different Army Staff “S” – designated numbers:

S-1 = Personnel
S-2 = Intelligence
S-3 = Operations
S-4 = Logistics
S-5 = Executive Officer
S-6 = Commander

So, we know that “Six” or “6” is the commander of a unit. “Nudge Blue Six” means:
Commander of 3rd Battalion of the 39th Infantry Regiment.

In the report above we also see “Omaha”. This is the call sign for the 3rd Armored Division

Corps and Army Call Signs:

VII Corps: Jayhawk
