Midway through WW II we used the American phonetic alphabet that went
Able
Baker
Charlie
Dog
Easy
Fox
George
How
Item
Jig
Kate
Love
Mike
Nan
Oboe
Peter
Queen
Roger
Sugar
Tare
Uncle
Victor
William
X-Ray
Yoke
Zebra
We switched sometime in the 1960s to the current NATO standard. So no Irene there.
Before the move to the US one, we had
Ack
Beer
Cork
Don
etc., or in other words, the British phonetic alphabet. Not sure why the switch; guys in the various "D" Companies were reportedly pissed at being referred to as "dog" though...
