You are right, it means On The Move. But it means On Mission too. ;p
And as far as I know, it isn’t even really used to say things faster. (I mean, how is Whiskey Tango Foxtrot shorter than WTF?)
I’ve been told, the walky-talkys were so crap back then, that ‘On the move’ or ‘on mission’ could be misheard sometimes… Which Oscar Mike was much clearer…
But seriously, is there a Change.org for this petition? I’ll make one myself if I have too! ;p
