Interceptor multi-threat body armor system

IBA was designed in the late 1990s as a replacement for the PASGT vest and the essentially-improvised ISAPO supplemental armor plate carrier, a combination widely criticized by US troops for its immense weight.

[3] The U.S. Marine Corps has replaced the OTV with the Modular Tactical Vest (MTV) and Scalable Plate Carrier (SPC), although IBA is still used by the U.S. Navy for sailors aboard its warships as of 2017 and by the U.S. Army Reserve as of 2018.

The IBA system consists of an Outer Tactical Vest (OTV) and two Small Arms Protective Insert (SAPI) ballistic plates.

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 cannot, however, be called a Level III-A vest, since military standards do not require protection against heavy .44 Magnum ammunition.

The vest will stop lower velocity fragments and has removable neck, throat, shoulder, extended back and groin protection.

SAPI and ESAPI are the most technically advanced body armor fielded by the U.S. military, and are constructed of boron carbide ceramic with a Spectra shield backing that breaks down projectiles and halts their momentum.

Materials for the Interceptor vest were developed by DARPA in the 1990s, and a contract for production was awarded to DHB Industries' Point Blank Body Armor, Inc., by the U.S. Army Soldier Systems Center.

[15] In 2007, news reports were being issued on the lack of protection from hard and soft plated body armor from lethal rounds.

As part of U.S. President George W. Bush's $87 billion package for ongoing operations in Afghanistan and Iraq, $300 million was earmarked for body armor.

[28] The MTV provides greater coverage, superior weight distribution, and additional features including as a quick-release system.

[30] Body armor is always a compromise: mobility and comfort (and with it speed and stamina) are inevitably sacrificed to some degree when greater protection is achieved.

This is a point of contention in the U.S. armed forces, with some favoring less armor in order to maintain mobility and others wanting as much protection as is practical.

Troops who primarily ride in vehicles generally want the highest practical level of protection from IEDs and ambushes, while dismounted infantry often make the case that impaired mobility can prove just as fatal as inadequate armor.

[17] On 4 May 2005 the U.S. Marine Corps recalled 5,277 Interceptor OTVs made by DHB's Point Blank unit after news reports about the vests' inability to stop 9 mm bullets.

In November 2005, the Marine Corps ordered 10,342 Interceptor outer tactical vests pulled from the operating forces after media reports indicated some samples tested by the manufacturer and by the U.S. Army's Aberdeen Proving Ground in Maryland failed to fully comply with ballistics standards.

[19] In 2005, the DoD, under severe pressure from Congress after the recalls, authorized a one-time $1,000 reimbursement to soldiers who had purchased civilian body armor and other gear.
