and powerful engines. When constructed, the NIFV will be lighter than other IFVs, including the American Bradley series and Russian BMP series, increasing both speed and payload. The ROK Army also fields the mobile K-SAM "Pegasus"(천마/天馬; Cheonma), fitted with 8 missiles that fly at maximum speeds of Mach 2.6, and the K-30 "Biho" series, which features a 30mm twin gun system for anti-aerial fire support. Besides having vehicles and equipment of their own design as well as American models, the ROK Army also possesses inventories of Russian-built AFVs, including BMP-3 IFVs and T-80U MBTs, given by the Russian government to pay off the financial debt owed to South Korea. Other notable foreign equipment in service with the ROK Army includes the Mistral MANPADS. In 2015, it was reported by South Korean lawmakers that more than 58,000 out of 100,549 South Korean soldiers at the Korean Demilitarized Zone lacked body armor capable of protection from North Korean firearms. The possession of only 42,030 body armor sets leaves 58,519 soldiers without body armor, and only 3,147 of the 42,030 sets are capable of protection from the AK-74, the standard assault rifle of the Korean People's Army. A new infantry rifle, the Daewoo K11, entered service in 2010. The overall concept of this weapon is more advanced to the American OICW, however its production has been halted and weapon discontinued in 2020 due to excessive issues involving its targeting component and the quality of ammunition, to focus on fixing the issues which have been quickly resolved. Inspection of military equipment June 2021 found that 26% of components involving the Warrior Platform program for modernization of South Korean infantry is defective.
