xm25--similer weapon to mst weapon.

I've bet, all of you have read the news of the latest weapons being used by the US soldiers in Afghanistan.
It's MX25.. which is a grenade launchers & shoulder-fired
weapons that uses microchiped ammunination to fired and kill
the enemy with precision. To me, it looks the same and do the similar job to the latest weapons being tested, successful in eliminating the enemy with accuracy. Yet, MST
weapontary has gone no where. Not winning any contracts
or being sold to any nations who are interested in such
weapons. Maybe only the other partiescould be interested to
purchase the weapons to counter XM25., Being the share-holders for 12 years and still no result.
