http://blog.naver.com/ichuka/51268352 XM-29 OICW (USA) K-11 (South Korea) With M16A2 operator kill rate of 70 to each XM-29 OICW operator lost, in combat simulation (1999). 1 : 70. Excellent!!!! But the XM-29 was canceled. Why? ---------------------------- XM-29 OICW (USA) weight 8.2 kg loaded (actual) 6.8 kg loaded (Objective) Overall length: 890 mm Unit cost 35000 dollars XM1018 length 92mm--weight 92.13g The 20mm HEAB for the XM-29 didnt seem to be lethal enough. ------------------------ K-11 (South Korea) 7.2 kg loaded Overall length: 860 mm Unit cost 16000 dollars K-594 length 100mm--weight 110g Increased destructive power of 20mm HEAB by technology improvement. K-11's 20mm HEAB can kill in 6-8m diameter, and wound in 16-20m diameter. Size of several hundred fragments is similar to grenade's. Fragments can penetrate US kevlar helmet and korea bulletproof vest in 6-8m diameter. So, K-11 will enter service this year (2009). K-11 is not 40mm grenadiers replacement. We will use both weapons. 40mm grenadiers----2 per a squad K-11 operator------1-2 per a squad
