The Modular Tactical Vest or (MTV) is a ballistic 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.
In July 2013, the Marines announced it will buy 3,800 Improved Modular Tactical Vests. The IMTV is made for smaller stature Marines who cannot wear the full-sized MTV comfortably. The vest comes in small-short, medium-short, and large-short sizes. Most Marines use the Scalable Plate Carrier in the field, so it is hoped that the additional sizes will encourage Marines to wear the IMTV in combat. The Corps does not want to design female-specific body armor, and has found that the issue was different statures related to the length of the torso. The IMTV can fit women, as well as smaller stature men.
