Why choose 70 series as rocket launcher? Not Hilux or whatever?
Only 70 series can handle the job? I doubt so.
I can actually give you some inside information - reason there is so many TLC 79 and I believe the 72/73 (two door with the softtop) being used by the rebel forces, is because they were "free", and by free I mean stolen.
The government had just taken delivery of a huge amount of them from the ME imported and they were in the process of issuing out to the different government sectors when the rebel force came in and stole them.
The dealers (before it was a big no no to ship armored or soft skins to libyia) were told to shop inbound shipments as they could not garranty they would not be highjacked and stolen also. Right now there is a GCC Toyota dealer with a number of 70 series that have already been paid for and they are unable to resell or refund the funds so they are just sitting there.
