Americans have 2,60,000 Humvees! Thats why they are able to maintain the fight wherever they go. We may say America lost in Afghanistan but its not true, imagine being fighting for 20 years at a place geographically 180 degrres opposite to USA, where there are jihadis ready for suicide attacks etc. Their total casualties are around 2800 deaths. Or 140 a year or only 1-2 every day in such a difficult environment. If we use Humvee like vehicles in Kashmir, we can save our soldiers from majority of ambush attacks.
