| Version 'zulu' is the military equivlent of 'Greenwich Mean Time' - GMT. Using the abbrev for GMT over a radio - it's too easiely lost in transmission and using the full name is too long. 'Zulu' is easily understood over a radio and keeps everyone on the same timeframe.
Very important if you're doing an internation mission or one that spans several 'time zones'.
I just think it was cool that they researched it enough to use that and use it right.
