OK, heres a link to Defense Update. This is a factual military mag which outlines the effect these weapons have.
For the less "Clued up" guys, they are a small fragmentation bomb, designed to be fired at an object close to the enemy, where they will shatter & disable.

You will find that this weapon has been designed specifically to reduce collateral damage. Not increase it.
