The Improved Outer Tactical Vest (IOTV), is an enhanced version of, and a replacement for, the older Outer Tactical Vest variant of the Interceptor body armor, as fielded by the United States Army. The IOTV is compatible with the Deltoid and Auxiliary Protector System (DAPS) components, ESAPI (Enhanced Small Arms Protective Insert), Enhanced Side Ballistic Inserts (ESBI), as well as the OTV's groin protector.
The OTV design was considered insufficient and lacking in certain areas, which led to the IOTV's development and fielding. The IOTV is currently produced by Point Blank Body Armor, BAE Systems, KDH Defense Systems, Protective Products Enterprises, UNICOR and Creative Apparel Associates. The IOTV first saw action in combat with U.S. Army ground combat units in late 2007/early 2008 and currently remains the standard body armor type used by regular U.S. Army ground combat units overseas.
A size Medium IOTV weighs 33.6 pounds, less than a Medium OTV vest, while providing more coverage. However, a fully equipped IOTV, complete with all its components (soft armor panel inserts, four ballistic plate inserts (front and back plates and two side plates), collar, and groin protectors) still weighs 30 pounds (13.6 kg), with a Large IOTV weighing about 35 pounds (15.9 kg). The functionality of the enhanced side ballistic inserts, which provide coverage under the arms and down the sides of the torso, is built into the IOTV.
Interceptor body armor (IBA) is a bullet-resistant vest that was used by the United States Armed Forces from the late 1990s to the late 2000s, still seeing use as of the early 2010s. The Interceptor Body Armor design replaced the older standardized fragmentation protective Personnel Armor System for Ground Troops (PASGT) body armor system, introduced in the early 1980s.
The Interceptor body armor system consists of an Outer Tactical Vest (OTV) and two Small Arms Protective Insert (SAPI) ballistic plates. The OTV features a carrier shell, and three main ballistic panel inserts (left and right side panels, and a rear back panel), which are made with a finely woven Kevlar KM2 fiber. These two parts of the vest are both bullet and heat resistant. The soft ballistic panels are produced in five different sizes (S-XXL), which are installed into their respective pocket on the OTV carrier shell.
The Interceptor armor also has a PALS webbing grid on the front of the vest which accommodate the same type of pockets used in the Modular Lightweight Load-carrying Equipment (MOLLE) backpack/carry vest system. This allows a soldier to tailor-fit his MOLLE and body armor system. While not specifically designed for it, the loops can also easily attach All-purpose Lightweight Individual Carrying Equipment (ALICE)-based equipment, as well as many pieces of civilian-made tactical gear, and also features a large handle on the back just below the collar which can be used to drag a wounded person to safety in an emergency.
