Fans of old movies may recognize and prefer to use this form, used by the US armed forces up to 1954: 

Able Baker Charlie Dog Easy Fox George How Item Jig King Love Mike Nan Oboe Peter Queen Roger Sugar Tare Uncle Victor William Xray Yoke Zebra. 



Ex-service personnel will recognize even earlier forms like the RAF form used in 1943: 

Apple Beer Charlie Dog Edward Freddy George Harry Ink Jug/Johnny King Love Mother Nuts Orange Peter Queen Roger Sugar Tommy Uncle Vic William X-ray Yoke/Yorker Zebra. 



Here's an even older variant, used by the Royal Navy during WW I:
