Arjun has been known for having a number of problems in the past. Dont known to what extent these problems have been fixed by DRDO???
Also dont know about its performance in the deserts, and that may be one of the main reasons IA has been reluctant to induct arjun.
But one thing i am sure of is, this beast has got one hell of an armour protection. and secondly it has leatheal fire power, but there has been some problems with its accuracy in the past. If that has been rectified, I think Arjun has a fair chance of finding its place in IA, no metter they like it or not, it will be very hard for them to find grounds for its rejection.
