What you are referring is to company modification, but I was hinting at field customisation where US troops were adding metal sheets to their Humvee.
Field Modification often resulted in the Humvee losing its centre of gravity.
Take the Humvee during IRAQ war troops had the possibility to customise their vehicles something like adding additional armour.
But it seems Indian 4x4 cannot take on such "customisation" am I rite in this analysis?
