These trucks have been launched very recently - 6X6 High-Mobility MAV's will be inducted in the Indian Army Service Corps for the very first time - not sure "which" trucks you actually came across in 2009.
Which truck was it? - was it a 4x4 drive or 6x6 drive? The only dedicated TATA truck for personnel/troops transportation are the Tata 407 Troop Carriers in service with the ASC since 1986, available in hard top, soft top, 4×4, and 4×2 versions. I am sure you can recognize those - the followng has been used in Indian peacekeeping operations - was it the one?
You never can.
There are no indigenous trucks in PA's inventory - the "Hinopak" he is talking about is nothing but a subsidiary of Japan's Hino Motors Limited - even Indian Army's inventory features Hino Super Dolphin FZ9J.
Considering that all what he said is true and he served in those peacekeeping operations in any capacity (certainly not a professional or ex-servicemen - his juvenile post suggest so) - I won't be surprised if TATA's 407 trucks weren't up to the mark - they are the same dairy trucks being used to supply milk to the outlets all across India - you must have come across one - the one above is frequently seen in construction sites - they weren't supposed to serve anywhere outside India in the first place and they all are pretty old designs dating back to 1980's.
But according to his logic - he considers these brand new MAV's won't work out since those 407's has some problems - it's just like saying Windows 7 sucks coz Windows Vista wasn't up to the mark - an argument far from reality.
Anyways the bottom line is - these MAV's have passed through a total trial duration of 25 months, demonstrating maximum performance in the most demanding conditions - enough to serve their purpose. The good thing is BEML-Tatra Trucks are losing their monopoly in the Indian Army.
