Mmmmm ....
Carsick .... get a grip on reality .... Mil 17 if your life is going to revolve around warzones .... for a REAL working career the 139 is the way to go ...
ALSO the 139 systems will be transferring to the 189 which most likely will be the machine of choice for so many operators into the future.
IMO ... Its a no brainer!
