You're not bulletproof...

Daewoo K11 Someone mentioned this rifle/grenade launcher combination. It is very reminiscent of the OICW program. Interesting as it is, whether or not the South Koreans have addressed the problems that plagued the OICW remains to be seen over time. Now considering the cost…a government issued M4 or M16 with the M203 launcher will be under $3,000 USD for the military. The K11 has an estimated cost of $14,000 USD per unit. This makes it highly unlikely that the K11 will become a standard issue firearm, more of a support weapon. It’s a worthwhile step towards new firearm designs. To quote the article and review of the K11… Problems with the U.S. OICW included fragment size and dispersion radius upon detonation.  In simple terms, the fragments of the 20mm munition were too small to be very effective.  In addition, there was insufficient explosive material within the 20mm OICW round to create an effective killing radius.  Finally, when detonated in airburst mode, the rules of physics resulted in the majority of fragments being dispersed vertically and away from the intended target, rendering the fragments ineffective.  These three issues worked in conjunction to kill the U.S. OICW program.   It is unknown whether Poongsan has addressed this issue within the K11 20mm munition design.
