There's two lingo types. THe army one, and the international aircraft one. Not sure about the army, but the air one is...
A - Alpha
B - Bravo
C - Charlie
D - Delta
E - Echo
F - Foxtrot
G - Golf
H - Hotel
I - India
J - Juliet
K - Kilo
L - Lima
M - Mike
N - November
O - Oscar
P - Papa
Q - Quebec
R - Romeo
S - Sierra
T - Tango
U - Uniform
V - Victor
W - Whiskey
X - Xray
Y - Yankee
Z - Zulu
I think that's right, but as always, willing to be corrected. I think the army code uses "baker" instead of "bravo" and probably a few other changes.
