And according to it, GSQR has now been formed, so on what specs was DRDO making light tank, imo most likely similiar to type 15 tank and hence very less likely to be amphibious cos being amphibious itself puts a lot of roadblocks towards effective Armor design.
Anyone here to bet that DRDO light tank might get cancelled even if it's the same as type 15.
Where are they going to find a light tank with amphibious, only nation i know is china and that too are assault gun platform not light tank.
Another important point being that K9 based light tank has been junked.
