Hmm to be honest i also don't likes BIS lacking of accuracy when it comes to proper designations of units/used units in general of certain branches.
It would be no problem for BIS in doing it right, by just renaming that MLRS to HIMARS and add proper round count - problem solved.
Then that Exhaust pipe of Hummer from right to left side and all is good, or not?
Maybe its gsm jammer
