Think about nano explosions. It is probably very light weight so the metal has to be very thin. So if a suicide bomber detonates inside a nano think of the devastation it will cause. It will definitely be a hit in Afghanistan specially with the Talibans and the suicide bombers.
It is so cheap that they will probably do some test explosions just to see nano's performance and how far does its pieces scatter after the blast. I imagine that the american might have to ban the nano for their own well being and security.
After all nano blasts they will say It was a Nano Hit.

Bam Bam. Thank You Tata Man
