There's a whole history to this alphabet and various different versions of it.
It's all out there on the web if you are interested in that. I've just put this up here 'cause I keep needing to remember it in the middle of a phone call and wish I had it with me... so here it is.
Without the readability gap, the words are:
Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Osca, Papa, Quebec, Romeo, Siera, Tango, Uniform, Victor, Whisky, X-ray, Yanky, Zulu.
