High Quality Content by WIKIPEDIA articles! The Modular Tactical Vest or (MTV) is a bulletproof vest originally adopted by the United States Marine Corps in 2006. The MTV was designed as a solution to shortcomings in the current, decade-old interceptor body armor (IBA) and was selected after a rigorous proposal and examination process by the Marine Corps. The MTV provides better protection levels than the IBA, although it uses the same Small Arms Protective Insert (SAPI) plates. The MTV weighs 30 pounds; three more than the IBA, but is designed to more effectively distribute its weight throughout the wearer`s torso. The Navy also ordered 28,000 MTVs in August 2008.
